Web1. Find the exact values of the following functions using the addition and subtraction formulas (a) sin 9ˇ 12 (b) cos 7ˇ 12 2. Write the expression as the sine or cosine of an angle. (a) sin ˇ 2 cos ˇ 7 +cos ˇ 2 sin ˇ 7 (b) sin5xcosx cos5xsinx (c) cos5xcos7x sin5xsin7x 3. Simplify the following expressions as much as possible (a) tan (9ˇ ... WebThis is called an addition formula because of the sum A+B appearing the formula. Note that it enables us to express the sine of the sum of two angles in terms of the sines and cosines of the individual angles. Key Point sin(A+B) = sinAcosB +cosAsinB We now want to look at sin(A− B). We can obtain a formula for sin(A− B) by replacing the
