Rigorous Gradient Tool More applets

This Java applet computes the value and the gradient of a function at a given point.


The function f(x,y) can be chosen freely, using the standard arithmetic operations +, -, *, /, ^ (integer power) and the standard functions sin, cos, exp and sqrt. The point (x,y) at which the function is evaluated can also be chosen by the user. Numerical constants are either floating point constants like 3.141, or intervals formed by such constants, for example [3.141, 3.142]. Intervals may also be used in the definition of the function.
