In this video, using A = 45° and B = 30°, we find the exact value of sin 75° using the principles of compound angles.
We use:
75° = 45° + 30° and the compound-angle formula:
sin(A + B) = sin A cos B + cos A sin B
Follow the solution step by step to find the exact value of sin 75° without using a calculator.
