Sina Sinb formula can be derived using addition and subtraction formulas of the cosine function. It is used to find the product of the sine function for angles a and b. The result of sina sinb formula is given as (1/2)[cos(a - b) - cos(a + b)]....
Formula for 2SinASinB is written as the difference of thecos(A - B)andcos(A + B). Therefore, the trigonometric formula for 2SinASinB is given by, 2SinASinB = cos(A - B) - cos(A + B), for compound angles A + B and A - B. Using this formula, we have the formula for sin...
