Math question

25 cos(2t)+12 sin(t+π/2)+2 cos^2(t)

cos(x-y) / sin(x)sin(y) = cot(x)cot(y)+1

The angle theta is in the first quadrant and sin of theta = 2/sqrt(13) determine the possible coordinates for point P on the terminal arm

Using either the sums as products or products as sums to work out the answer.

Is it that the line of the tangent in the graph will be a continuous or broken

if sin of A = 5/13, in quad 1, find tan A/2 if cos of A = -4/5, in quad 2, find sin A/2 if cos A =-4/5 in quad 2, find cos A/2 if cos A - -4/5 in quad...

I missed this class so I'm really confused on how to solve this.

I am doing sum and difference formulas with sin, cos, and tan. I am doing tan75 with the difference formula. So tan 120-45 I have all the things found I just don't know...

Solve the equation 8sin(1/2)x - 5 = 0 for 0 < x < 2pi. Round your answers to the nearest hundredth of a radian.

State the amplitude and period of this function: y = -3cos(pi/3)x.

State the amplitude and period of this function: y = 4sin(1/2)x
