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.)
