Taking a derivative at a point HP 50g

[A_Fiorito]

I am new to using the HP 50g and I am curious about its differentiation ability.

I know how to use the calculator to take the derivative of functions but I would like to know if there is an easy way to do it at a point.

For example, how could I differentiate x*sin(x) at x = 0?

Use the vertical bar (right shift TOOL), for example:

'∂X(X*SIN(X))|(X=0)'
