Trig verifying identities
I am having trouble with this problem. sec^2(pi/2x)1= cot ^2x I got : By cofunction identity sec(90 degrees  x) = csc x secx csc1 = cot^2x Then split sec x and csc1 into two fractions and multiplied both numerator and

1) verify the identity sec^2 (pi/2  x) 1 = cot^2 x I think that we can replace sec with csc for the cofunction formulas since there is pi/2. Since there is squared and a 1 I think we could use one of the pythagorean identites

Verify the identity. (csc(2x)  sin(2x))/cot(2x)=cos(2x) =csc(2x)/cot(2x)  sin(2x)/cot(2x) =csc(2x)/cot(2x)  cos(2x) Is this correct so far? If so then how would I continue? I got stuck on this part...

I'm trying to verify these trigonometric identities. 1. 1 / [sec(x) * tan(x)] = csc(x)  sin(x) 2. csc(x)  sin(x) = cos(x) * cot(x) 3. 1/tan(x) + 1/cot(x) = tan(x) + cot(x) 4. csc(x)/sec(x) = cot(x)
