Indefinite Integral Calculator (u-substitution)
Introduction & Importance
Indefinite integrals are a fundamental concept in calculus, and the u-substitution method is a powerful tool for solving them. This calculator simplifies the process, allowing you to focus on understanding the underlying concepts.
How to Use This Calculator
- Enter the function you want to integrate in the ‘Function’ field.
- Enter the substitution ‘u’ in the ‘u’ field.
- Enter the derivative of ‘u’ with respect to the original variable in the ‘du’ field.
- Click ‘Calculate’.
Formula & Methodology
The u-substitution method involves replacing part of the integrand with a new variable ‘u’ and its derivative ‘du’. The formula for integration by substitution is:
∫f(g(x))g'(x) dx = ∫f(u) du
