sin(x)cos(x-60)=0

Solution

sin (x) cos (x - 6 0^{\circ}) = 0

Solution

x = 36 0^{\circ} n, x = 18 0^{\circ} + 36 0^{\circ} n, x = 36 0^{\circ} n + 15 0^{\circ}, x = 36 0^{\circ} n + 33 0^{\circ}

Radians

x = 0 + 2 πn, x = π + 2 πn, x = \frac{5 π}{6} + 2 πn, x = \frac{11 π}{6} + 2 πn

Solution steps

sin (x) cos (x - 6 0^{\circ}) = 0

Solving each part separately

sin (x) = 0 or cos (x - 6 0^{\circ}) = 0

sin (x) = 0 : x = 36 0^{\circ} n, x = 18 0^{\circ} + 36 0^{\circ} n
