Using the cosine formula for addition, we get this ... Notice that the left side of the equation has a sum but the expanded formula on the right side of the equation has a minus sign. The cosine formula is strange in this regard. The left side and the right side of the equation ...
Calculate sine by dividing the leg across from the acute angle in the question by the hypotenuse of the triangle. In other words, sin(theta) = O/H, where O is the opposite leg and H is the hypotenuse. What is the sine and cosine formula? The sine formula is sin(theta) = O/H, ...
