Formula for 2SinASinB is written as the difference of the cos(A - B) and cos(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...

Product to Sum Formulae Sometimes it is useful to be able to write a product of trigonometric functions as a sum of simpler trigonometric functions (this might make integration easier, for example). Now, cos(A + B) = cosAcosB - sinAsinB and cos(A - B) = cosAcosB + sinAsinB Adding ...
3., a and B on both sides of the triangle are known. The angles of both sides are C, and S = 1/2 * absinC, that is, the sine value of the angle between the two sides of the product.4. triangle, three sides are a, B, C, and the radius of inscribed circle is R Then the...
It is deeply understood that all of the following trigonometric formulas can be derived from here, for example, to derive Sin (A+B) = sinAcosB+cosAsinB, for example: Deduction: First, draw the unit circle, cross the X axis at C, D, and have ...
