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)
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 range is {-5, -2, 1, 4}
The equation (-\tan A = \tan A) is true only when (\tan A = 0). This occurs at angles where (A) is an integer multiple of (\pi) (e.g., (0, \pi, 2\pi), etc.). In general, (-\tan A) is not equal to (\tan A) for most values of (A). Thus, the statement is not universally true.
