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)

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)

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)

sin2Ø-1 = 1 ...

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

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...

csc2(x) sec(x)=?

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

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

Use the graph to complete the identity. cos (x) tan x - 2tan x +5cos x-10/tan x +5= A.) cos x - 2 B.) sin x + 5cos x C.) sin x - 5 D.)...

Use the half-angle formulas to determine the exact values of the sine, cosine, and tangent of the angle. 7π/12 5 sin(7π/12) = 9 cos(7π/12) = 5 tan(7π/12) =

5 sin2 x csc2 x − 5 sin2 x

This is a trigonometry identity problem.

Thisis a trigonometry identity problem.

I'm trying to figure out how to simplify this equation.

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.

Prove the identity

Please Help. Establish Identity: sin(x+y)/tan(x)+tan(y)= cos(x)cos(y)

simplify each of the following: cos2 x * tan2 x + cos2 x
