1. It is not the function of this webpage to simply do the homework or assignments for students.
It sure looks like that is what you want.

These look like routine questions for a standard Calculus course.

I will do #2 the way I would do it, follow this procedure to do the rest.

5cos(2pi x)=3
cos(2pi x)=3/5 = .6

so the angle (2pi x) is either in quadrants I or IV according to the CAST rule

then (2pi x) = .9273 OR (2pi x) = 2pi-.9273 = 5.358

then x = .14758 or x = .8524

Now the period of your original function is 2pi/2pi = 1

So in the interval from 0 to 3
x = .14758, 1.14758, 2.14758, .8524

(I tested all of them, they work)
