Sin A Cos B Solution

Follow our step by step solution on how to calculate Sin A Cos B?

FIRST Step Consider the formula

sin A  cos B = \frac{\sin (A + B) + \sin (A - B)}{2}

Next Step Substitute values of Variables

∴

sin A  cos B = \frac{\sin (20° + 30°) + \sin (20° - 30°)}{2}

Next Step Convert Units

∴

sin A  cos B = \frac{\sin (0.3491rad + 0.5236rad) + \sin (0.3491rad - 0.5236rad)}{2}

Next Step Prepare to Evaluate

∴

sin A  cos B = \frac{\sin (0.3491 + 0.5236) + \sin (0.3491 - 0.5236)}{2}

Next Step Evaluate

∴

sin A  cos B = 0.296198132725987

LAST Step Rounding Answer

∴

sin A  cos B = 0.2962
