graphing trigonometric functions...
sin and cos seem to work easily, but i'm having trouble getting the tangent function to graph (look) correctly...?
???
thank you

Re: Graph Tangent Function
Can you post and example workbook?
Re: Graph Tangent Function
You have to plot it in two sections, from -pi/2 to pi/2, and from pi/2 to 3pi/2, all exclusive of the end-points (infinities).
Re: Graph Tangent Function
thank you...
i think the problem is when excel evaluates the points tan(pi/2) and tan(3pi/2)...?
(it should be undefined and not graph...)
???
thank you.
Re: Graph Tangent Function
It's probably some combination of the Taylor Series (?) used to compute the value and precision issues for pi/2.
