2tan-1 ([√(a-b)÷√(a+b)] ×tan (x\2 )) = cos -1 (acosx+b/a+bcosx)

2tan-1 ([√(a-b)÷√(a+b)] ×tan (x\2 )) = cos -1 (acosx+b/a+bcosx)

Find the derivative of tan-1(1/t) I have seen other answers online but they are really hard to follow. I thought you would need to use the product rule. Not...

this problem by all accounts seems unsolvable. because you get 136 and and that isn't in between 180 and 270. What am I doing wrong??

Evaluate In degrees: 1. Sin^-1 (-2pi) 2. arctan (- square root 3/3) 3. sin (cos^-1(- square root 3/2) Evaluate in...

Find the inverse of the function and also the domain. f(x) = 12sin(14x)

sin(alpha) = 0.195946 implies alpha = tan(beta) = 0.818491 implies beta = sec(theta) = 2.5913 implies theta = Find the following to one decimal place. Show me how you...

A drone plane moving at 70m/s, flies horizontally at an altitude of 400 meters directly over a radar station. Let 'O' be the angle of elevation of the drone. What is the rate of change of the angle...

Here is my equation: cosA=b/c. Now, I want to isolate A on the left-hand side. It is my understanding that cosA is a calculated value. "A" has a degree value, but cos has no numerical value...

Cos does not have any numerical meaning by itself, but cosA has a distinct value. If we multiply that value by its inverse, I can understand how we produce an answer of one. But how does that process...

If M&m are maximum and minimum values of f(x), then thier arithmetic mean is equal to

I believe that calculators are not allowed, because the final answer is supposed to be exact. Thanks

solve for x

I dont get how to do this, the problme is sinx=.3 you have to take the inverse of n.3 and you get .305 (round) but the i dont know where to go from there, you need 2 solutions and .305...

Find the formula for the inverse of the function.\\ f(x)=(1+ex)/(1-ex•) f-1(x)=

please answer, i dont understand how to go about this problem.

Simplify. Please i need help! p- stands for Pi (radians). and yeah, its like this (a.cosx - b.sinx) / (b.cosx + a.sinx). Amd Tan^(-1) stands for the tangent inverse (tan inverse). We need...
