Taking a derivative at a point HP 50g - Printable Version +- HP Forums (https://www.hpmuseum.org/forum) +-- Forum: HP Calculators (and very old HP Computers) (/forum-3.html) +--- Forum: General Forum (/forum-4.html) +--- Thread: Taking a derivative at a point HP 50g (/thread-15534.html) Taking a derivative at a point HP 50g - A_Fiorito - 09-03-2020 06:17 PM 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)' EVAL EVAL RE: Taking a derivative at a point HP 50g - A_Fiorito - 09-10-2020 01:46 AM (09-03-2020 11:02 PM)ijabbott Wrote:   (09-03-2020 06:17 PM)A_Fiorito Wrote:  I am new to using the HP 50g and I am curious about its differentiation ability.
