Cos A Sin B Solution

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

FIRST Step Consider the formula

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

Next Step Substitute values of Variables

∴

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

Next Step Convert Units

∴

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

Next Step Prepare to Evaluate

∴

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

Next Step Evaluate

∴

cos A  sin B = 0.469846310392885

LAST Step Rounding Answer

∴

cos A  sin B = 0.4698
