Can someone help me with these?

1. Simplify, listing reasons: cos^2 theta times csc theta + sin theta.

2. Given the stated information, sketch theta and find the exact values.

a. cos alpha(in degrees) = -1\2, 180 degrees < alpha < 360 degrees, find alpha, sin value and tan value.

b. If sin^-1 (squareroot of 3 over 2) = alpha^R ad alpha^R lies in quadrant II, find alpha^R, cos value and tan value.

c. tan alpha^R = -1/root3, pi < alpha < 2pi, find alpha, sex value, and csc value

d. sin alpha(in degrees) = 0, 90 degrees < or = to alpha < or = to 270 degrees, find alpha, cos value and tan value.

e. sec alpha^R = root 2, pi < alpha < 2pi, find alpha, cot value and sin value
