Best ResponseYou've already chosen the best response.113pi/6  2pi = 13pi/6  12pi/6 = pi/6 which is an angle in the first quadrant. You can find the cosine of pi/6 from the standard 30/60/90 triangle . The secant is = 1 / cosine.

Best ResponseYou've already chosen the best response.12pi  7pi/4 = 8pi/4  7pi/4 = pi/4 . This is an angle in the 4th quadrant where the tangent is negative. You can find the exact values by considering the standard triangle 454590 . The cotangent = 1 / tangent.
