Example Find all solutions to sin 3x sin 2x with 0 x 2 First we bring everything to one side of the equation sin 3x sin 2x 0 Next we use a sum to product formula from section 5 4 of our textbook to rewrite the left side of our equation as a product The relevant formula is sina sin 2 sin In the equation we re solving a Select a which means that B 2 a 2 Select x Select Select a x cos a 2 2 and 3 Our rewritten equation now looks like this 5x and
