A point on the terminal side of angle θ, is given. Find the exact value of the indicated Trigonometric Function of θ.
(9,12); Find the sin θ.
You need to find r, the length of the hypotenuse. Use the Pythagorean Theorem. . We determine that r = 15.
Since we know that sin of an acute angle in a right triangle is the ratio of the opposite side of the angle divided by the hypotenuse, we can say:
