Question

Suppose that the terminal side of an angle in standard position passes through the point (sqrt(3), -6). Use the point-in-the-plane description to find the exact value of sin(t), cos(t), and tan(t).

Answer 1

first you need the radius of the circle. then cosine is the first coordinate divided by the radius, sine is second coordinate divided by the radius

do you know how to find the radius of the circle?

Answer 2

\[r=\sqrt(x^2+y^2)\]?

Answer 3

yes exactly

Answer 4

Okay, I'll work from there and ask if I need some more help. Thanks!

Answer 5

ok good!
