Question

How do you sketch the angle whose terminal side in standard position passes through (0,3) and how do you find sin and cos?

Answer 1

sin t = 1
cos t = 0

Explanation:

Call t the arc (or angle)
`tan t = y/x = 3/0` --> infinity
The point (0, 3) is located on the y-axis.
Therefor, `t = pi/2`
`sin t = sin (pi/2) = 1`, and
`cos t = cos (pi/2) = 0`
