Substitution rule for integrals

About this app

Integration by substitution with examples: the x-area is distorted into the u-area by u = g(x) (g′(x) explains dx → du), both areas stay equal in size. In sync, the calculation step by step — find the inner function, differentiate, substitute, convert the bounds.
