I am getting stuck at 7 plus or minus sqrt 309 / 26 13sin^2x-7sinx=5 solve for interval [0,360degrees]

they are squared and to the power of 4

4 sin x cos x - 2√3 sin x - 2√2 cos x +√6=0 interval 0≤x<2pi

This is translated from a trigonometry problem in another language, I hope you understand it.

(1-(2(cos^2))(43.5°))/((sin84° sin7°)−(sin6° sin277°))

Proving identities

show that 1/(1-cos x) - 1/(1+cos x)=2cosec x cot x

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

I know how to get the answer, but for some reason, they want it in this format and I'm not sure how to do it this way.

Its two questions Prove if this is true or false 1-sinϴ • cosϴ •tanϴ=cos^2ϴ and cos^2ϴ • tanϴ= sinϴ

If sin(x) = 1/4 and x is in quadrantI,find the exact values of the expressions without solving for x. (a) sin(2x) (b) cos(2x) (c) tan(2x)

There are 2 possible answers I can choose from. Either Bounded or Continuous

I know this is with the sum-to-product identity, but I need help with the steps.

Hello! I am having some trouble verifying a trig identity sin(4x)=4cos^3(x)sin(x)-4sin^3(x)cos(x)

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

verify the trig identity plz help!!!

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,...

Given that sin(a)=2/3 and cos(b)=-1/5, with a and b both in the interval of pi - pi/2

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!
