Homework Statement
Sketch the regions enclosed by the given curves.
y = 3 cos 6x, y = 3 sin 12x, x = 0, x = π/12
Find the area as well.
Homework Equations
The sketch of the curve is given too which I uploaded.
The Attempt at a Solution
Trouble finding intersection points
3cos(6x)= 3sin(12x)
cos(6x)=sin(2*6x)
cos(6x)=2sin(6x)cos(6x)
0=cos(6x)(2sin(6x)-1)
0=2sin(6x)-1
sin(6x)=1/2
6x=sin^-1(1/2)
x=(sin^-1(1/2))/6
Then I am not sure what to do from here.
