+50 Let P, Q, R, and S be the terminal points on the unit circle below:
Let a, b, c, and d be angles such that P = Terminal point for a, Q = Terminal point for b, R = Terminal point for c, and S = Terminal point for D.
a) Order the angles a, b, c, and d such that their sines are in increasing order.
b) Order the angles a, b, c, and d such that their cosines are in increasing order.
c) Order the angles a, b, c, and d such that their tangents are in increasing order.
Could someone provide an explanation for this? I'm really confused. Thank you!
