Prove sec2x-1=sec2xsin2x, justify significant steps. (state identities used)

Please help me answer the following question! I'm stuck! Prove that cos6ß + sin6ß = 1/4 + 3/4cos2ß I've tried simplifying out the LHS into (cos2ß)3 + (sin2ß)3,...

This is my work. tanx = -2sinx sinx/cosx = -2sinx sinx = -2sinxcosx (multiply by cosx) 1 = -2cosx (divide...

Using Pythagoras, and making reference to a right angle triangle.

sinh x = (e^x-e^-x/2) and cosh x = (e^x + e^-x/2)

1) 2sec x =4.6 2) 3cos^2 x + cos x-2 =0 3) Sech x =0.554

Prove sin4z = [4tanz(1-tan2z)]/(1+tan2z)2

verify the trig identity plz 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!

Verify the Identity.

Using angle A=53.13 and angle B=36.87 find an algebraic expression for tan theta =tan (a-B) in terms of x. x= 12 m

Using angle A=53.13 and angle B=36.87 find an algebraic expression for tan theta =tan (a-B) in terms of x. x= 12 m

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.

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

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.

Use the trigonometric identities to write each expression in terms of a single trigonometric function. A. Sin^2 D. (tan^2 +1)Sin^2 Cos^2 B. cot +1 E. 1+ 1 tan +1 cot^2 C. Sin^2 +cos^2...

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...

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