Using the unit circle we looked at yesterday, use these values when trying to find exact values of trig functions.

Example 1 a) Find the exact value of sin 135° .

Example 1 b) Find the exact value of cot 11𝜋 2 .

Example 2 – You try Find the exact value. a) cos 210° b) tan 225° c) csc −120° d) cot 7𝜋 3

Example 3 The swing arms of the ride pictured below are 89 feet long and the height of the axis from which the arms swing is 99 feet. What is the total height of the ride at the peak of the arc?

Example 4 – You try The swing arms of the ride pictured below are 68 feet long and the height of the axis from which the arms swing is 79 feet. What is the total height of the ride at the peak of the arc?
