Cosx-1=sinx

verify the trig identity plz help!!!

if sin theta is equal to 3/5 on the interval (pi/2 , pi), what is tan 2 theta?

 if sin theta is equal to 3/5 on the interval (pi/2 , pi), what is tan 2 theta?

How to solve (sinx/1-cscx)-(sinx/1+cscx)= -2cot^2x?

I need to set the problem sides equal to each other. A step-by-step guide would be helpful. My entire class doesn't understand it.

Help with trigonometric proofs. I really need help.

a) (sinx-tanx)/(cosx-cotx)=〖tan〗^2 x((cosx-1)/(sinx-1))   b) (cos^2x-sin^2x)/sinxcotx-cosxtanx)= cosx + sinx   Please show work. Thank you so much!

These are multiple questions that I need help with. Numbers 1.( Ask to simplify) 2-6 (ask to multiply and simplify) and 9-14 ask to find angle sum and difference.    Note: I'm also...

(Siny - cosy) (siny + cosy)

I need to simplify using Pythagorean identities I need hel asap

((sin(a)cos(b)-cos(a)sin(b))^2)+((cos(a)cos(b)+sin(a)sin(b)^2)

I need some help with the steps to solving this, I know that I need to foil out the problem but I need to get a numerical value for the expression. 

How do you simplify sin(x)tan(x)+ cos(x)?

A step-by-step guide would be very appreciated. Thank you in advance.

1/1-cos^2 theta = 1 + cot^2 theta

Verify the Identity. 

(tan w + 1/sec w) = sin w + cos w

Verify the Identity

(sin^2x)(1+cot^2x)=1

Verify the Identity. 

(cos B/cot B) + (sin B/tan B) = sin B + cos B

Verify the Identity. 

Use trigonometric identities to transform the left side of the equation into the right side.

sin^2x-cos^2x=2sin^2x-1   (tanx+cotx)/tanx=csc^2x

Proving Trig Identity

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