Question

Let (-5,2) be a point on the terminal side of theta . Find the exact values of cos(theta), sin(theta), and tan(theta).

Answer 1

what is missing is the length of the hypotenuse, which you find via pythagoras
do you know it?

Answer 2

ya i know it... so do you just need to use it to find the hypotenuse then use opp/adj and such?

Answer 3

yes exactly
be careful of the signs though don't just use the lengths, i.e. remember the \(-5\) when you take "adjacent over hypotenuse"

Answer 4

alright will do
