prove\:\tan^2(x)-\sin^2(x)=\tan^2(x)\sin^2(x) \frac{d}{dx}(\frac{3x+9}{2-x}) (\sin^2(\theta))' \sin(120) \lim _{x\to 0}(x\ln (x)) \int e^x\cos (x)dx \int_{0}^{\pi}\sin(x)dx
The arctan(x) is equal to the inverse tangent function: tan⁻¹(x). If in a right triangle, the tan of the angle determines the ratio of the perpendicular to the base (tan(x) = perpendicular / base), then arctan will help us find the value of the angle x: x = tan⁻¹(perpendicular / base).

In computing and mathematics, the function atan2 is the 2-argument arctangent. By definition, θ = atan2 ( y , x ) {\displaystyle \theta =\operatorname {atan2} (y,x)} is the angle measure (in radians , with − π < θ ≤ π {\displaystyle -\pi <\theta \leq \pi } ) between the positive x {\displaystyle x} -axis and the ray from the origin ...
The arctangent function is differentiable at every \(x \in \mathbb{R} .\) Moreover, if \(f(x)=\arctan (x),\) then \[f^{\prime}(x)=\frac{1}{1+x^{2}}.\] Proof. The result follows immediately from Theorem \(7.5 .4 .\) \(\quad\) Q.E.D.
