Can someone please explain the Substitution Rule to me in easier terms? I am soooo confused!
Thanks,
Allison

The substitution rule is a mathematical technique used to evaluate integrals that involve a variable substitution.
The substitution rule allows for the simplification of complex integrals and makes it easier to evaluate them.
The substitution rule works by substituting a variable in the integral with another variable or expression, in order to make the integral easier to evaluate.
Sure, for example, if we have the integral ∫(2x + 5)dx, we can use the substitution u = 2x + 5 to rewrite the integral as ∫u du. This makes it easier to evaluate the integral using basic integration rules.
Yes, the substitution rule may not work for all integrals. It is important to carefully choose the substitution variable in order to simplify the integral. Additionally, some integrals may require multiple substitutions to evaluate.
