how do you integrage 1/x^2 or 1/x^3 .

Also How would you solve for partial integrals? because there are partial integrals as well as there are partial derivatives right?

would anybody refer me to a basic webpage for integrals? I'm not talking about any of the other methods like substitution or integration by parts, just regular basic integration like for the equation above, I know basic integration but forgot what to do in some cases.

Triangle ABC is an isosceles triangle with the measure of angle B = the measure of angle C, and the measure of angle A = 20 degrees. Points D and E are located on sides AC and AB, respectively, so the the measure of angle CBD = 50 degrees and the measure of angle BCE = 40 degrees. Determine the measure of the angle BDE.
