## What is the arctangent of 2 ?

arctan 2 = ?

The arctangent is the inverse tangent function.

Since

tan 1.107 = tan 63.435º = 2

The arctangent of 2 is equal to the inverse tangent function of 2, which is equal to 1.107 radians or 63.435 degrees:

arctan 2 = tan^{-1} 2 = 1.107 rad = 63.435º

And we are still developing more. Our goal is to become the one-stop, go-to site for people who need to make quick calculations or who need to find quick answer for basic conversions.

Additionally, we believe the internet should be a source of free information. Therefore, all of our tools and services are completely free, with no registration required. We coded and developed each calculator individually and put each one through strict, comprehensive testing. However, please inform us if you notice even the slightest error – your input is extremely valuable to us. While most calculators on Justfreetools.com are designed to be universally applicable for worldwide usage, some are for specific countries only.
