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
The first one, I don't even know where to start, considering I wasn't taught it, but was still given it.
The second one, I don't know how to start it, nor how to graph it. I just honestly don't get it, and I don't think I was taught it quite yet.. For a, I'm guessing you graph -1/2 (how though?) and I don't know what the 180 < alpha < 360 is?
Ohhh okay, I get that now.. makes such more sense!
