Determine the solution(s) to the equation root3tantheta + 3 = 1 where 0</=theta</=2pi.

Is sin2xsinx-cosx = -(3root3)/2 true for 7pi/6? Explain.

Determine the solution(s) to the equation root3tantheta + 3 = 1 where 0</=theta</=2pi.

Is sin2xsinx-cosx = -(3root3)/2 true for 7pi/6? Explain.   Here is what I got: sin(2(7pi/6)) = root3 / 2 (0.86602540378) sin(7pi/6) = -1/2 (-.5) cos(7pi/6)...

Determine the exact angle(s) of theta if cos theta = -3/root2, where 0</=theta</=2pi.

If theta is in standard position and 0 </=theta</=2pi, determine the value of tan theta, if sin theta =3/5

cos x(2sinx + sqr root 3)(-sqr root 2 cosx + 1) = 0

Assume the point (-2, 10) is on the terminal side of an angle in standard position.

sin(x+y)/sin(x-y)=(a+b)/(a-b) then tanx/tany=?

A surveyor determines that the angle of elevation to the top of a building from a point on the ground is 26.2 degrees. He then moves back 53.9 feet and determines that the angle of elevation is 18...

(31/2)sinx+cosx

Cos2 (2x) - cos2 (6x) = Sin(4x)sin(8x)

tan4x=(4tanx(1-tan2x))/(1-6tan2x+tan4x)

Sin2 (6x) - Sin2 (4x) = sin(2x)Sin(10x)

I am not havin g any idea to solve it.

I'm not asking what it does, and I'm not looking for "tan(angle)=opposite leg/adjacent leg". I'm asking what the actual function is. For instance, using degrees (not radians) tan(22.5)=20...
