Hi,
I would like some help evaluating the following integrals.
I'm not sure if I am doing all the right steps.
∫

Thank you
Show us the steps you've done and where you think you may be wrong.
The first one may be easily done by integration by parts knowing that INT(cos^2(t) dt) = [x + sin x cos x]/2.
The second one requires from you to know INT(ln x)dx , which can be done straight integrating by parts, and also to put x^2 + 14x + 49 = (x+7)^2 and use some basic properties of logaritms.
