The arctangent of x is defined as the inverse tangent function of x when x is real (x∈ℝ).When the tangent of y is equal to x:tan y = xThen the arctangent of x is equal to the inverse tangent function of x, which is equal to y:...

The limit of arctangent of x when x is approaching infinity is equal to pi/2 radians or 90 degrees: The limit of arctangent of x when x is approaching minus infinity is equal to -pi/2 radians or -90 degrees: Arctan ►
反三角函数为啥叫arcXXX In the inverse trigonometric function arctan, the term arc is used because when measuring an angle in radians, the arc length of a part of the circle bisected by an angle (with the vertex at the center of the circle) equals the angle measure. The radian is the ...

So what then is the arctangent function? Quite simply, this function does the reverse of the tangent function: the arctangent of a number is an angle whose tangent ratio would be equal to that number. The arctangent function is represented symbolically by the abbreviation {eq}\arctan {/eq...

Hi, I was just looking at an example for a certain problem and noticed that in the second step they went to arctan(epsilon). I know there's a form that is equal to arctan but am a little unsure. I've come across formulas on the web such as arctan(x) = ∫(dt)/(a2+t2) but...
