does anyone know how to graph trig functions, specifically tangent equations, in Excel? I have a math project and it would be alot less messy to do the graphs on the computer. when ever i put in tan(x+4) or any other number it says it doesnt work because there is a variable in it. Thanks for any help.
 
Yeah I think you can only have one number in the tan function - should be plenty of google stuff on this?
 
I looked on google but there wasn't much on how to do it. most of the stuff was jsut telling about tan functions
 
Oh I see, so you want to be able to graph the whole equation

I would think that you might need an addon pack?

I remember when I was doing a lot of statistical work, that was the only way to be able to do what we needed
 
Ya I'd probably look up an addon pack or find a different graphing program. I don't think excel is a big fan of variables in functions. Could you maybe set up a table with varying X values? Like in 15 degree increments (or in rads, however you're doing it) and then take the tangent of those values? It will give you data points that you could graph on a curve and then fit a trendline too which should out put your original function.
