Question

Suppose an angle α is drawn in standard position. In each case, use the information to determine what quadrant α is in.
Note: An angle is in standard position if it is drawn on the xy-plane with its vertex at the origin and its initial side is on the positive x-axis.

(a) sin(α) > 0 and cos(α) > 0.(Select all that apply.)

Answer 1

sin refers to "y-value"
cos refers to "x-value"

on a graph for both x and y to be positive, you must be in the ___?____ quadrant

Answer 2

Thank you so much! Do you know what the tan, sec, and csc refer to?

Answer 3

tan = sin/cos
= y/x
so on for others

Answer 4

Thank you
