Trigonometry Identities and equation

solve the equation for the solutions over the interval [0 degrees, 360 degrees) 6sec2xtanx=12tanx I am unsure of where to begin.

This question is about to prove some trigonometric identities

cos(3theta)=-1 solve for exact solutions over the interval [0,360 degrees] I am having trouble finding a place to start.

prove that tan6.tan42.tan66.tan78=1

Proving identities

sinxcos^4x+cos^6x=

Find the exact value algebraically of sin(105°)

cos(2θ) = 1/√2 (1 divided by square root 2) 90° ≤ θ ≤ 180°

(sinx)/(cosx-sinx)=cotx+1, find x

Hi, this is my first time using this site. So I have been staring at this trigonometric equation for a long while and looking for what it asks for. For what I know, I think I have to use sum of...

Solve step by step to get the answer

tan34/2(1-tan34) =(2/2)[tan34/2(1-tan34) =2tan34/4(1-tan34) i need to have the form 2tanA/1-tan^2A but i cant eliminate the 4

The question is- In a △PQR, if 3sinP+4cosQ = 6 and 4sinQ+3cosP=1, then the angle R is equal to:

tana+tanb/1-tanatanb im confused becase sqrt of 3 over 3 is the value of tan 30 so its hard to solve the arithmetic and the algebra. help please!

Sin(45-x)=cos(45+x) How to prove this identity?

Prove sin4x = 4 (sin x-2 sin^3 x)/secx I can't seem to solve this! Halp!!!

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