About Calculus

Calculus is the mathematics of change and accumulation. Differential calculus studies rates of change (derivatives), while integral calculus studies accumulated quantities (integrals). Together, they provide the mathematical language for physics, engineering, economics, and data science. Calculus builds directly on algebra and trigonometry, so strong foundations in those areas make all the difference.

Popular topics in Calculus

How ScanSolve helps with Calculus

ScanSolve handles calculus problems from AP Calculus AB through multivariable. For derivatives, it identifies which rule to apply, shows the chain rule decomposition for composite functions, and simplifies the result. For integrals, it selects the right technique — u-substitution, parts, or partial fractions — and explains why that technique fits.

For application problems like related rates and optimization, ScanSolve starts by drawing out the relationships, defining variables, writing the equation to differentiate or optimize, and then solving step by step. It explains the meaning of the answer in context — for example, that the derivative equals zero at a maximum.

For series, it walks through convergence tests systematically, explaining why a particular test was chosen and what the result tells you. This structured approach mirrors how calculus exams are graded, maximizing your score on free-response questions.

Study tips for Calculus

1. 01

   Drill derivative rules until they are automatic. Speed on basic differentiation frees up mental bandwidth for harder parts of the problem, like setting up related rates.

2. 02

   For integration, always try u-substitution first. It solves the majority of integrals you will encounter, and recognizing the substitution gets faster with practice.

3. 03

   Draw pictures for every application problem. Volumes of revolution, area between curves, and related rates all become much easier when you can see what you are computing.

4. 04

   When studying series, make a flowchart of convergence tests. Knowing the decision tree — geometric? p-series? ratio test? comparison? — saves time on exams.
