Derivative

CalcES allow to calculate both symbolic derivative and or a derivative at a point.

Example

dxd2x2=4x

dxd2x2∣∣∣x=2=4×2=8

Numeric derivative

To enter numeric derivative template, press SHIFT ∫dx

Fill out the numeric derivative template, example (Input is in RAD angle unit):

To enter symbolic derivative template, press 2nd d/dx

Fill out the symbolic derivative template, for example:

dxd(sin(x2)+cos(2x))=2xcos(x2)−2sin(2x)

The input is in the RAD angle unit

$symbolic derivative of \frac{d}{dx} (\sin(x^2) + \cos(2x))$
