Question 182252This question is from textbook saxon algebra 2
: Point Q is located on the terminal side of angle 0 with a dash through it and has coordinates (-8,6). Find the exact value of the six trigonometric functions for 0 with a dash through it.
I have figured it out to be sin=6/10, cos=-8/10, tan=-6/8, csc=10/6, sec=-10/8, cot=-8/10. My questions are am I correct, and should they be in simplest form?

You can put this solution on YOUR website! Point Q is located on the terminal side of angle 0 with a dash through it and has coordinates (-8,6). Find the exact value of the six trigonometric functions for 0 with a dash through it.

-------------------------
Since x = -8 and y = 6, r = sqrt(64+36) = sqrt(100) = 10
---------------------
So:
sin(theta) = y/r = 6/10
etc.
You could put them in simplest form; they are correct.
