How do you sketch the angle whose terminal side in standard position passes through #(1,sqrt3)# and how do you find sin and cos?
If you place the triangle on a graph, with one side laying on the positive side of the x-axis, and set the other side to pass through the origin and the given point
The bottom side will be the "adjacent" side to the angle, while the vertical side is the "opposite."
knowing the acronym SOH CAH TOA
and the Pythagorean Theorem
We can find that
By solving for Hyp, we see that the hypotenuse is 2 units long.
Knowing this, we can then solve the sine and cosine.
