SFU Math 157 is Calculus I designed specifically for students in social sciences programs—economics, business, psychology, sociology, and related fields. It covers differential calculus (limits, derivatives, optimization) with applications tailored to economic models, marginal analysis, elasticity, and social science contexts. Unlike Math 151 (which focuses on physics and engineering), Math 157 connects calculus directly to the questions social scientists ask: How do we optimize profit? What happens when demand changes? How do we model human behavior mathematically?
What is covered in SFU Math 157?
Math 157 introduces differential calculus with applications to social sciences. Topics include:
- Functions and models: Linear, exponential, logarithmic, and polynomial functions in economic and social contexts
- Limits and continuity: Understanding behavior of economic and social functions
- Derivatives: Definition, differentiation rules (power, product, quotient, chain rule)
- Applications in social sciences: Marginal analysis (cost, revenue, profit), elasticity of demand, and optimization
- Optimization problems: Finding maximum profit, minimum cost, and optimal allocation of resources
- Exponential and logarithmic functions: Growth models, compound interest, and logarithmic scales
- Implicit differentiation: Finding derivatives when functions aren't explicitly solved for y
- Related rates: Modeling how rates of change interact in dynamic social systems
Math 157 is typically followed by Math 158 (Calculus II for Social Sciences) and is required for many economics, business, and social sciences programs.
Common challenges students face in Math 157
Economic context feels unfamiliar
You're not just learning derivatives—you're applying them to marginal cost, revenue functions, and elasticity. If you don't understand the economics, the math feels disconnected.
Optimization problems dominate
A huge portion of Math 157 is about finding optimal values: maximum profit, minimum average cost, optimal production. These problems require setting up equations correctly, taking derivatives, and interpreting results in economic terms.
Word problems are everywhere
Exams are heavy on applied problems. You need to read an economic or social scenario, extract relevant variables, set up the appropriate function, differentiate, and solve—all while managing time pressure.
Conceptual questions
Exams don't just ask "find the derivative." They ask "What does the derivative represent economically?" and "Explain why the profit is maximized at this point." You need to understand concepts, not just compute answers.
How Learn4Less helps you succeed in Math 157
Our tutors understand both the calculus and the social sciences applications.
Step-by-step problem solving
We guide you through marginal analysis, optimization, and elasticity problems from start to finish. You'll learn how to read economic scenarios, identify the right approach, and solve efficiently.
Contextual understanding
We explain the economics and social science behind the math. When you're working with cost functions, revenue optimization, or elasticity, you'll understand why the equations make sense—not just how to manipulate them.
Exam-focused strategies
We teach you how to interpret social science questions, write clear economic explanations (which earn partial credit), and manage your time across problem sets.
Math 157 exam and midterm preparation
Math 157 typically has midterms and a final exam. Here's how we prepare you:
Practice with social sciences applications
We focus on the types of problems that appear most often: marginal analysis, optimization in economic contexts, and elasticity of demand.
Past exam walkthroughs
We work through previous years' exams so you know what to expect. You'll practice reading economic scenarios, extracting key information, and solving efficiently.
Conceptual fluency
We drill you on explaining derivatives in economic terms: "What does this marginal cost represent?" and "How do you interpret this maximum value in business terms?" These questions appear on every exam.

Frequently Asked Questions
What's the difference between Math 157 and Math 151?
Math 157 is designed for social sciences students, with applications like marginal cost, revenue optimization, and elasticity. Math 151 is for physical sciences and engineering, focusing on mechanics and physics. The core calculus is similar; the applications differ.
Can I take Math 151 instead of Math 157?
Check your program requirements. Math 151 is often accepted as equivalent, but it's more physics-focused. If you're an economics or business major, Math 157's applications will be more relevant and useful.
Do I need high school calculus to take Math 157?
Not necessarily. Math 157 assumes some familiarity with functions and algebra, but many students succeed without prior calculus. If you've never seen derivatives before, review exponential and logarithmic functions before the course starts.
Is Math 157 easier than Math 151?
No. Math 157 covers similar mathematical concepts but applies them in economic and social contexts. If you're not comfortable with economics, the word problems can feel harder than pure math. Neither course is "easy"—they're just aimed at different audiences.
When should I get a tutor for Math 157?
As soon as you feel confused or fall behind. The course moves quickly, and concepts build on each other. Many students wait until after the first midterm to seek help, but by then, catching up is much harder. Proactive tutoring from week one is the smartest strategy.
