just curious if anyone knows where there is online graphing program that will graph trig function with radians on the x axis

tried Wolfframapha but not

thanks ahead

This is a very odd question. Radians are not actually units. They are just numbers. If the x-axis is not specifically labeled otherwise, it is "Radians".

ok but typically on trig functions you see the x axis in terms of pi that what I was looking for. Wolffram does do it but only on certain functions, there is no way to set it for that

What do you think $$\pi$$ is, a platypus?

$$\pi = 3.14159265358979323846264338...$$

It's not a platypus. It's a Real Number.

Please clarify karush, but what I think you're referring to is a graph where the x-axis would have labels such as $$\displaystyle 0, \frac{\pi}{2}, \pi, \frac{3 \pi}{2}$$ and so on. I'm not aware of such a calculator but I would point out that you can easily convert any point you are looking at to something "in terms of $\pi$" by taking that number and dividing it by $\pi$.

Let me know what you're looking for if I assumed incorrectly but in the meantime I would definitely recommend an online calculator called Desmos. It is by far the best online graphing calculator that I know of, it's free and I am in contact with their development team if there are ever any issues.

Obviously you are looking for a program where you can label the axes in multiples of $$\pi$$ or any other value (for instance $$\sqrt{3}$$ or else).

I use the program Graph (have a look here: Graph | Plotting of mathematical functions). It's a Danish program which is available in many different languages. I use - of course - the German version.

I've attached a screen-shot of the sin-function where you can see how you can adjust the labeling of the axes.
