Grapher Help (well math help)

[36183]

i need to draw a tan line graph for my math homework, and actully drawing one it rather hard (well not really hard, just annoying with all the drawing of the curves)

i am trying to draw one with the grapher app but i dont know what to type in to get a tan line graph thing.

someone help, please.

thanks in advance.

Whats the funtion yoo are calculating tan?, i think grapher has a n option to draw a tan curve, but if it doesnt have, just post your function, and i give you the rect eq. You always can do that by hand, just derivate.

I am gonna see if Grapher has the tan option.

yeah a tan curve that is what i ment to say.

That help?

yes it did indeed.

now just delete this thread unless my math teacher finds it

I don't know what you plan to use these graphs for but it may save you some confusion if you take note that, as Grapher does calculus too, it defaults to using radians instead of degrees.

This can be changed in the advanced section of preferences.

(Sorry if I sound condescending; I don't know what level of math you are taking.)

i am doing high level GCSE. my math teacher just told us to draw some sin,cos and tan graphs and i cant be bothered to actually draw them.

we should start doing some more serious work soon.

Hmm. Might I suggest actually learning why the curves look like they do so that next time you won't have to rely on macrumors and a computer to graph a trigonometric function?

This will come in handy later. They are all infinitely cyclical. Sin and Cos are very closely related to as you will notice that one is just a translation along the x-axis of the other.

Maybe you could try graphing sin(x)/cos(x) and see what you get...

i know why the curves look the way they look. i do listen in math class. i just cant be bother to draw them.

Well I'm sure your "this is below me" attitude will take you far in your high level math course. Good luck.

i just dont want to draw the curves, it is so dam hard to get right.

and thanks for wishing me well

Heh. You are correct, Curves are tough to get Right.... Angles however, are another matter.

Alright, I'm done.

The sin, cos and tan graphs are actually very easy to sketch.
TAN: Draw vertical asymptotes at every 180º on the x-axis (starting at ±90º), and then start from 0,0 point, draw a flat bit and then simply asymptote them up to infinity (to +90º) and -infinity (on negative side). Due to the nature of the TAN graph, you could never "draw" it unless you had an infinitely big piece of paper! Just sketch man, that's what their after!

Just don't ask what root loci and frequency response curves can look like!
