I am very confused as to what identity I need to use to simplify this equation.

When verifying trigonometric identities, can you multiply both sides by a number to make it easier to solve?

A: -√(17/24) B: -√(7/24 C: -√(7/6) D: -√(17/6

Use knowledge of trig identities to find the trig value below. If csc α = 5/2 , find sec α cot α

prove (1 - cos2x)(1 - tan2x) = sin2x cos2x/1-sin2x I got as far as.... Using the left side: (1 - cos2)(1 - tan2) (1 - cos2)(1 - sin2/cos2) 1 - cos2 - sin2/cos2...

I have a math problem in which I have to prove the identity sin2θ= 2tanθ/1+tan2θ using Double-Angle Identities and I'm trying to figure out how to solve it.

If csc ∝ = 7/4, find cos∝cot∝ + sin∝. Please include steps. I don't know how to go about this one.

My math is online and the helper says that sin∅= y/r= (5√74)/74 = 144.5° . how do u convert that fraction into degrees. I did try the inverse of ∅=sin-1(y/r) , but for my example that...

Proved LHS is RHS

prove (1 - cos2x)(1 - tan2x) = sin2x cos2x/1-sin2x I can't seem to solve this! Halp!!!

to prove: (tan(x)+sec(x)-1)/(tan(x)-sec(x)+1)=sec(x)+tan(x)

Prove: tanA + cotB= cos(A-B) / cosAsinB

Write the following in terms of sin (theta) only: 2sec(theta)tan(theta)+tan^2(theta)

Prove that (cos x-sin x)/cos x = sin2x-tanx+cos2x Also is there any restrictions?

A) -1 B) 1 C) 0 D) undefined E) none of these

Provide an exact evaluation of the expression: tan (-285°).
