Proving a trig identity and I dont know what to do

I'm having trouble trying to prove this trig identity. Help is greatly appreciated. Thanks in advance. 1/(csc-cot) = (1+cos)/sin

How do you solve the problem?

Prove: 1/2(cotA-tanA) = cot2A

trig identitry

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

csc2(x) sec(x)=?

You have a right triangle and the hypotenuse is 10 and adjacent side is 6 and the opposite side is 8, this is what the triangle looks like except NO cm! http://www.cimt.plymouth...

sin2Ø-1 = 1 ...

options a. cot u =sin (u)/cos(u) b. sec(-u)=sec(u) c. 1+tan^2(u)=sec^2(u) d.cos (u)=1/sec(u)

the answer is (2 radical 3 - radical 5)/6 Just don't know how they got it.

Assume the terminal side of the angle falls in Quadrant 2. Show all work.

1.prove each identity sin (q)/1+sin (q)-sin q/1-sin(q)=-2 tan^ 2 (q) 2.(cos^2 q/1-sin q )- (cos^2/1+sin q)

If cos(2x)=4/5 and x terminates in quadrant 1, then find sin(x)

Prove the identity

explain why a horizontal compression of a trigonometric function will increase the number of solutions when solving that trigonometric function is part of an equation.

2 decimal places

Solve the given equation over the interval [0,2): 2sinx+ (sqrt 3) sin^2x=-(sqrt 3) cos^2x A. x=0, and x=(pi/2), and x=(3 pi/2), and x=2(pi)x=(3 pi/2), and x=(7 pi/2) b. x=(4 pi/3) and...

the book says the answer should be sinX /sinX+cosX
