Using the identity sin? 0 + cos² 0 = 1, find the value of tan 6, to the nearest hundredth, if sin 0 = -0.62 and 3 < 0 < 27.
The answers for part b are sin(A/2) = √26/26, cos(A/2) = -5√26/26, and tan(A/2) = -1/5, but I can't figure out how to get there lies and (b) find the 24. Iftan A = with 34 < A< 21, then (a) determine the quadrant in which exact value of sin (), cos (), and tan ().
in each case: (e) Compute y = sin(z)cos(r) for 0 < z < π/2
1. Use an identity to find the exact value of cos(?) given that cos(O) = { with 270° << 360°
