Mastering Differential & Integral Calculus Online
Calculus forms the backbone of advanced engineering, physics, continuous mathematics, and quantitative finance. Differential calculus studies rates of change and curve slopes, while integral calculus evaluates accumulated quantities and geometric areas beneath functions.
Similar to fnInt( and nDeriv( numerical commands on the physical TI-84 Plus CE calculator, our web-based calculus solver equips high school AP Calculus students and university engineers with instant verification tools for polynomial differentiation and definite integration.
Essential Calculus Rules & Formulations
- Power Rule for Differentiation: To calculate the derivative of a single monomial term
f(x) = c · xⁿ, multiply the coefficient c by power n and reduce exponent by 1:f'(x) = c · n · xⁿ⁻¹. - Definite Integration Formula: According to the Fundamental Theorem of Calculus, the definite integral of
xⁿfrom lower limit a to upper limit b evaluates the net area under the curve using the antiderivative evaluation:[xⁿ⁺¹ / (n + 1)]from a to b.
Step-by-Step Instructions
- For derivatives: Input the scalar coefficient c and power n into the input boxes and click Differentiate.
- For definite integrals: Input lower integration limit a, upper limit b, and power exponent n, then click Integrate to yield the area value.
Frequently Asked Questions (FAQ)
What does the derivative f'(x) represent geometrically?
