Tan2x Formula. Sin 2x, Cos 2x, Tan 2x is the trigonometric formulas which are called as double angle formulas because they have double angles in their trigonometric functions. Let’s understand it by practicing it through solved example. Tan2x=2tanx/1−tan2x. √a 2 + x 2: x = a tan θ : 1 – tan 2 θ = sec 2 θ √x 2 − a 2: x = a sec θ : sec 2 θ – 1 = tan 2 θ sin(2X) = 2 sinX cosX cos(2X) = 1 - 2sin 2 X = 2cos 2 X - 1 tan(2X) = 2tanX / [ 1 - tan 2 X ] Multiple Angle Formulas sin(3X) = 3sinX - 4sin 3 X cos(3X) = 4cos 3 X - 3cosX sin(4X) = 4sinXcosX - 8sin 3 XcosX cos(4X) = 8cos 4 X - 8cos 2 X + 1 Half Angle Formulas Formula $\tan^2{\theta} \,=\, \sec^2{\theta}-1$ The square of tan function equals to the subtraction of one from the square of secant function is called the tan squared formula. It is also called as the square of tan function identity. Introduction.

Then the arctangent of x is equal to the inverse tangent function of x, which is equal to y: arctan x = tan-1 x = y.
