Sin a + sinb

WebbSin (a - b) formula is also called the difference formula in trigonometry. The sin (a - b) formula for the compound angle (a - b) can be given as, sin (a - b) = sin a cos b - cos a sin b, where a and b are the measures of any two angles. Proof of Sin (a - b) Formula The expansion of sin (a - b) formula can be proved geometrically. WebbUsing this formula, we have the formula for sinAsinB given by, sinA sinB = (1/2) [cos (A - B) - cos (A + B)]. The image given below shows the 2SinASinB formula in trigonometry: If …
