MATHS 💯#### Hi,I really struggling with trigonometric equations and this is one of the questions I’m stuck on, thank you for any help. Solve sin(2x-60°)=0.5 for 0°≤x≤360°?

Applying arcsin to both sides: 2x - 60 = arcsin(0.5) Rearranging for x: x = 0.5(arcsin(0.5) + 60) arcsin(0.5) = 30 degrees All solutions of x: 45, 2...
