AI Thread Summary
The discussion centers on the calculation of sin 90° and tan 45°, with the original poster claiming the answer is 0, while the textbook states it is 2. The correct values are clarified: sin 90° equals 1 and tan 45° equals 1, leading to the correct sum of 2. The confusion arose from a misunderstanding of the unit circle values, particularly regarding sin 90°. The thread emphasizes the importance of accurately referencing trigonometric values to solve such problems correctly.

What is sin 90°? tan 45°? How exactly did you get those answers?
 
I am supposed to use the values from the unit circle. so sin90degrees would = -1
 
Really? Make sure you're going in the right direction.
 
oh silly mistake. thanks alot
