Integration by Substitution

Continuous functions of the form f'(x)g(f(x)) can be integrated by the technique of substitution. Substitution used is u=f(x). This GeoGebra applet obtains step by step integral by the technique of substitution. Check instructions to read instruction. Your input is required in f(x) and u(x) input boxes. Slider must be used to show the solution step by step. You are encouraged to verify each step manually. For more on integration of functions check my online book "Flipped Classroom Calculus of Single Variable"
