Answer:
Explanation:
The fundamental theorem of calculus can be applied to the proper integrals. I'm going to use the general formula:

I'm also going to assume you know the integrals of basic trig functions and 1/x. I cant prove them, you just have to know them.
a)

b) ln|x| --> ln(6) - ln(3) = 0.69
c) sin(Ф) --> sin(2pi) - sin(0) = 0
d)
-->
