## Using Derivatives in Interpolation
I apply the function
and interpolate the result.
Why is the resulting interpolation not smooth?
Data can be given in the form to specify derivatives as well as values of the function at the points . You can specify different numbers of derivatives at different points. Using this feature to specify the first derivatives of the function
and then interpolating
gives what you want.
Alternatively, you can use splines.
