First and Second Derivative of a Function

This HTML5 app is a function grapher that also draws the graphs of the 1st and 2nd derivative functions if desired. The following symbols can be entered:

xindependent variable
+plus
minus
*multiplied by
/divided by
^power
(...)bracket
abs(...)absolute value
sqrt(...)square root
exp(...)natural exponential function
ln(...)natural logarithm
sin(...)sine
cos(...)cosine
tan(...)tangent
arcsin(...)arcsine
arccos(...)arccosine
arctan(...)arctangent
sinh(...)hyperbolic sine
cosh(...)hyperbolic cosine
tanh(...)hyperbolic tangent
arsinh(...)inverse hyperbolic sine
arcosh(...)inverse hyperbolic cosine
artanh(...)inverse hyperbolic tangent
eEuler's number e
picircle number π

Note that multiplication signs (*) must not be omitted. For example, 2*x has to be entered instead of 2x.
