MATH 1140 is Thompson Rivers University's general Calculus 1 — the differential calculus course for science and mathematics students, and the one most TRU students mean when they say "calculus". It is three credits, and TRU runs it in two timetable shapes: a 3-1.5-0 format with a tutorial, or a 5-0-0 format that packs the same content into five lecture hours with no scheduled tutorial. Which you get changes how much supported practice is built into your week, and it is worth checking before you register.
What is covered in TRU MATH 1140?
TRU's calendar describes MATH 1140 as differential calculus for functions of one variable, with applications emphasizing the physical sciences: calculation and interpretation of limits and derivatives; curve sketching; optimization and related-rate problems; l'Hospital's rule; linear approximation and Newton's method. In practice:
- Limits and continuity: one-sided limits, limits at infinity, and the cases where a limit fails to exist
- The derivative: the limit definition, and differentiability against continuity
- Differentiation rules: power, product, quotient and chain rules, implicit and logarithmic differentiation
- Transcendental derivatives: exponential, logarithmic, trigonometric and inverse trigonometric functions
- Curve sketching: increasing and decreasing intervals, concavity, inflection points, asymptotes
- Optimization: maxima and minima in applied settings, justified with the first or second derivative test
- Related rates: one rate from another, through a relationship you have to build first
- l'Hôpital's rule: indeterminate forms, and recognising which ones qualify
- Linear approximation: the tangent line as a stand-in for the function nearby
- Newton's method: finding roots by iteration, and when the iteration fails
Three credits, and the prerequisite is Pre-Calculus 12 with a minimum of 67% (C+), or MATH 0610, 0630 or 0633 with a C−, or MATH 1000 or MATH 1001 with a C−.
The credit exclusion you need to understand first
This is the single most consequential fact about first-year mathematics at TRU, and it catches people out every year.
TRU grants credit for only one of MATH 1130, MATH 1140, MATH 1141, MATH 1150, MATH 1157, MATH 1170 and MATH 1171.
All seven are Calculus 1 in some form — the general one, the engineering one, the distance one, the biology one, the business one. They are alternatives, not a ladder. You get one.
So if you take MATH 1170 for a business program and later switch to science, you cannot simply add MATH 1140 for credit. Take the decision seriously at registration, and check your program requirements rather than picking on the timetable.
Where MATH 1140 leads: MATH 1240 Calculus 2 accepts it with a C−, and MATH 1240 in turn opens MATH 2110 Calculus 3 (with a C) and MATH 2120 Linear Algebra 1. MATH 1140 is the standard route into TRU's mathematics and physical science sequence.
Common challenges students face in MATH 1140
Pre-Calculus 12 at 67% is a thin margin
The prerequisite is a C+, and a student who got exactly that is entering a course that spends algebra and trigonometry rather than teaching them. Time lost on factoring or an identity is time not spent on the calculus, and that is where a term quietly goes wrong. If this is you, MATH 1000 first is often the faster route overall.
The limit definition is learned once, then examined
Everyone uses the rules within a fortnight and never returns to the definition. Then a midterm asks for a derivative from first principles or why a function is not differentiable at a corner, and the rules do not help.
Related rates and optimization are reading problems
Both ask you to turn a paragraph into a relationship between variables and then differentiate. The calculus is the last two lines. The first eight — naming variables, finding the constraint — are where the marks go, and they are what nobody practises.
Newton's method and linear approximation get left out
They arrive late, they look like a different subject, and they are reliable marks. Skipping them is an expensive way to save an evening.
Five lecture hours with no tutorial is a different course to survive
If you are in a 5-0-0 section, nothing in your week is set aside for working problems with someone. That is fine if you build the habit yourself, and a slow disaster if you assume it will happen.
How Learn4Less helps you succeed in MATH 1140
We work from your section's material
Your assignments, your tutorial sheets if you have them, your instructor's notes. That is what you are marked on, not a generic syllabus.
We rebuild the algebra inside the calculus
If trigonometric identities or log laws are the real bottleneck, we fix them within the problem you are already stuck on, so you keep moving with the course.
We teach the setup for applied problems
Naming the variables, finding the constraint, deciding what to differentiate with respect to. Once that is written down, related rates and optimization stop being the hardest questions on the paper.
We can be the tutorial a 5-0-0 section does not have
For students in the five-lecture format, a standing weekly session working problems is often the whole of what is missing.
MATH 1140 exam and midterm preparation
Timed practice on unseen problems
Assessment weighting varies by section, so your course outline is the authority. What does not vary is that exam questions are unfamiliar by design, and that is what we practise against the clock.
Writing for partial credit
A correct derivative with no visible method can score less than an incomplete solution with clear reasoning. We work on defining variables, stating what is being differentiated, and keeping signs and units straight under pressure.
Justifying optimization answers
Setting the derivative to zero finds a candidate. Showing it is a maximum — second derivative or sign chart — is what earns the marks, and takes fifteen seconds once it is a habit.
Checking your own work between sessions
Our free derivative calculator works each step, so a long chain-rule computation that came out wrong becomes a specific line to look at rather than a mystery.
Why choose Learn4Less for MATH 1140 tutoring?
First-year calculus is our core subject
We tutor the first calculus course at UBC, SFU, KPU, UVic and TRU. The same handful of misconceptions recur across all five, which usually means we recognise yours in the first session rather than the fourth.
Sessions built around your own problems
Bring the assignment that is due, the question you could not finish, or the midterm you want to understand rather than file away.
Online across Canada and the US
TRU is in Kamloops, so sessions with TRU students run online — screen sharing and live work on a shared page, with the whole session written down for you afterwards. In-person tutoring is available in the Vancouver area only.
Free resources, no session required
The derivative calculator, the integral calculator and our concept reviews are open to anyone.
Frequently Asked Questions
What is the difference between MATH 1140 and MATH 1130?
MATH 1130 is Calculus 1 for Engineering, and its prerequisite is not a grade at all — it is admission to the Engineering program. MATH 1140 is the general science and mathematics course, open on the strength of Pre-Calculus 12 at 67% or an equivalent. The content overlaps heavily; the framing and the audience differ. They are credit excluded with each other, so you take whichever your program puts you in.
Can I take MATH 1140 after MATH 1170?
Not for credit. MATH 1170 and MATH 1140 are in the same credit-exclusion group, so completing one closes the other. If you are moving from a business program into science, speak to an advisor before you register for anything.
Do I need MATH 1000 first?
Only if you do not meet the prerequisite, or if Pre-Calculus 12 was a long time ago or went badly. MATH 1000 with a C− satisfies the prerequisite, and it is a legitimate choice even if you technically qualify — MATH 1140 assumes the pre-calculus is automatic, not merely passed.
Which Calculus 2 comes after MATH 1140?
MATH 1240 Calculus 2, which accepts MATH 1140 with a C−. MATH 1230 Calculus 2 for Engineering requires MATH 1130 specifically, so it is not the route from here.
When should I get a tutor for MATH 1140?
Before the first midterm rather than after. Calculus compounds — a shaky grasp of limits becomes a shaky grasp of derivatives, which becomes lost marks on optimization. Students who ask in week three are fixing one topic; students who ask in week eight are fixing four.
