Find 6 trig functions of (315)
Explanation:
On the trig unit circle,
sin (315) = sin (-45 + 360) = sin (-45) = - sin (45)
Trig table gives ->
cos 315 = cos (- 45) = cos 45 =
cot 315 = 1/tan = -1
sec = 1/cos = sqrt2
csc = 1/sin = - sqrt2
This is one of the usual suspects,
Explanation:
Step 1: First we fight the depression that comes when we see they've asked yet again a question about the two tired triangles of trig, 30/60/90 or 45/45/90.
Step 2: We apply various trig identities related to coterminal and negated angles and do the problem.
Typing that is like practicing scales on the piano. Question writers, please give us another triangle.
