The Inverse Tangent Function
by Mike Martin

On this page, you can vary the parameters in the arctangent function (the inverse function for the tangent function). Once the parameters are set you can plot the function and its first and second derivatives. Submit real values for all of the parameters. Use at your own risk as some parameter values may produce erroneous graphs, but parameters consistent with the literature will work.

The arctangent function may be written as

f ( t ) = arctan ( a t )
or

f ( t ) = tan-1( a t )

Enter in the value of the parameter a and select the plotting bounds, then press the "Evaluate" button.

a =  


  ≤   t   ≤  


  ≤   f (t)   ≤
