General solution
Cos^2 +3sin= 3

math  Reiny, Sunday, May 19, 2013 at 7:55am
cos^2 x + 3sinx = 3
1  sin^2 x + 3sinx + 3 = 0
sin^2 x  3sinx  4 = 0
(sinx 4)(sinx + 1) = 0
sinx = 4 , which is not possible
or
sinx = 1
x = 3π/2
since the period of sinx is 2π
general solution:
x = 3π/2 + 2kπ, where k is an integer.
