Question

The Chain Rule for antiderivatives is also known as the ___________________ rule.

 

-derivative

-substitution

-product

-integral

Answer 1

Suppose we had an integral such as

 

∫(2x - 5)^1/2 dx

 

 

This is not easy to integrate, as of now.  We use a method to ease the process.

 

If we let    u = 2x - 5     ,     du = 2dx         , and          dx = (1/2)du

 

 

then we are using substitution.
