Solve for x.

sin (2x) + cos (3x) = 1

 

[MathLover1]

sin (2x) + cos (3x) = 1

Graph each side of the equation. The solution is the x-value of the point of intersection.

cos^3(x) - 3 sin^2(x) cos(x) + 2 sin(x) cos(x) = 1

x≈2πn
x≈0.45138289+2πn
x≈3.69923776+2πn
x≈4.5016604+2πn

for any integer n
