cos(x)>0
And x will be in the first/fourth quadrants
cos(x)=12
x=cos1(12)=π3 is an angle in the first quadrant.
x=(2ππ3)=5π3 is an angle in the fourth quadrant.

What is the general solution to the equation sinx+3cosx=2
I need to find the general solution to the equation
sinx+3cosx=2
So I went ahead and divided by 2, thus getting the form
cos(xπ6)=cos(π4)
Thus the general solution to this would be
x=2nπ±π4+π6
Which simplifies out to be,
x=2nπ+5π12
x=2nππ12

Proving right hand side to left hand side:
csc2x+2cscxcotx+cot2x=1sin2x+2cosxsin2x+cos2xsin2x (1)
=cos2x+2cosx+1sin2x (2)
=1sin2x+1+sin2xsinxsin2x (3)
=2sinxsin3x+sin2xsinxsin2x (4)
=2sinxsin3x+sin2xsin3x (5)
I could not prove further to the left hand side from here.
