y = 2*tan(2x) is an equation in two variable. There can be no answer. While x can be made the subject of the formula, that is not an *answer*.
The principal range of arc tan is an angle in the open interval (-pi/2, pi/2) radians = (-90, 90) degrees.
Cotan(theta) is the reciprocal of the tan(theta). So, cot(theta) = 1/2.
either cos OR tan-sin equals zero socos=0 at pi/2 and 3pi/2ortan=sin which is impossibleim not sure though
tan(b) = x/sqrt(y^2-x^2)
The range is {-5, -2, 1, 4}
tan theta = sqrt(2)/2 = 1/sqrt(2).
Yes, that is a shifted tanX graph, just as you would shift any graft.
This would be a real bear to prove, mainly because it's not true.
The domain would be (...-2,-1,0,1,2...); the range: (12)
