We then define the cosine and sine of the arc t as the x and y coordinates of the point P so that P t cos t sin t we abbreviate the cosine as cos and the sine as sin Textbook Question Write each expression in terms of sine and cosine and then simplify the expression so that no quotients appear and all functions are of only See Example 3 tan cos Verified Solution This video solution was recommended by our
The sine and cosine of an acute angle are defined in the context of a right triangle for the specified angle its sine is the ratio of the length of the side that is opposite that angle to the length of the longest side of the triangle the hypotenuse and the cosine is the ratio of the length of the adjacent leg to that of the hypotenuse All the trigonometric identities are based on the six trigonometric ratios They are sine cosine tangent cosecant secant and cotangent All these trigonometric ratios are defined using the sides of the right triangle such as an adjacent side opposite side and hypotenuse side
