What is arctan? Arctangent is the inverse of the tangent function. For an in-depth analysis of the tangent, visit our tangent calculator. Simply speaking, we use arctan when we want to find an angle for which we know the tangent value.
7.3 CALCULUS WITH THE INVERSE TRIGONOMETRIC FUNCTIONS. The three previous sections introduced the ideas of one–to–one functions and inverse functions and used. those ideas to define arcsine, arctangent, and the other inverse trigonometric functions. Section 7.3 presents. the calculus of inverse trigonometric functions.

The Rule: . arctan. OR . arctan. Putting everything together: . Use this rule when you have a fraction of the form: where the polynomial in the denominator does . not factor and the fraction is not in the correct form to turn into an . Example: evaluate . From the example above we know that .

Arctan Formula. As discussed above, the basic formula for the arctan is given by, arctan (Perpendicular/Base) = θ, where θ is the angle between the hypotenuse and the base of a right-angled triangle. We use this formula for arctan to find the value of angle θ in terms of degrees or radians.
