Question
A point on the terminal side of an angle $\theta$ in standard position is given. Find the exact value of each of the six trigonometric functions of $\theta .$$$(-1,1)$$
Step 1
We can use the Pythagorean theorem to do this, which states that $r^2 = x^2 + y^2$. Here, x is -1 and y is 1. So, $r^2 = (-1)^2 + 1^2 = 1 + 1 = 2$. Taking the square root of both sides, we get $r = \sqrt{2}$. Show more…
