Review
Substitution Review
If u=g(x) is differentiable, then
()()=() if u=g(x) and du=g’(x)
Example a:
()
()
u=cos(2x)
du=-2sin(2x)dx
Solving so that cancellation is possible:
-
= sin(2)
Plugging in to the integral:
1
21
1 +
Solving this Integral:
-
arctan()+
Plugging u back in:
=
arctan(cos(2)) +
-Because -2sin(2x) is also in the
function, without the -2
arctan () = tan
