Hi I have a few questions, on how to solve these two intergral problems.
1) \(\displaystyle x^2/
sqrt(9-x^2) dx\)
With this problem I am suppose to use Rationalizing Substitution right?
sqrt(a2+x2) Substitution is x= a sin t
x= 3 sin t
dx = 3 cos t
sqrt(32−x2)dx = 3 cos t
2) x3/x2−2x+1dx
With this problem i am suppose to use proper rational function correct?
__A__ + __B__
(x-1)____(x-1)
Solve for a and b and then take the intergral correct?
