Name the first Pythagorean Identity.
What is sin^2(x) + cos^2(x) = 1
100
The simplified version of: sin(x)cos^2(x) - sin(x)...
sin^3(x)

What is tan^2(x) + 1 = sec^2(x)
200
[sec(x) + tan(x)]/sec(x) simplified fully
1 + sin(x)
200
Verify [cos^2(x) + (sin(x) + 1)^2]/[sin(x) + 1] = 2
Mr. Brown must check for proper verification!

What is (sin(x) - 3)(sin(x) - 2)
300
tan(x)/sec(x) + cot(x)/csc(x) = sin(x) + cos(x)
Mr. Brown will check the verification!
