Mathematical formulae

Is there a method of inserting mathematics in a post?

Toucan just type it.

There are subscript and superscript tools, so you can try your best. Or you could post an image of your equations.

According to John Davis you can use  jsTex bbcode. I don't know how that works!

Oh, here I found the post.

[jsTex]d(P_1,P_2) = \cos^{-1} \left( \sin \left(\tan^{-1} \left(\frac{x_1^2 + y_1^2 -1}{2x_1} \right) \right) \sin \left(\tan^{-1} \left(\frac{x_2^2 + y_2^2 -1}{2x_2} \right) \right) +\cos \left(\tan^{-1} \left(\frac{x_1^2 + y_1^2 -1}{2x_1} \right) \right) \cos \left(\tan^{-1} \left(\frac{x_2^2 + y_2^2 -1}{2x_2} \right) \right) \cos \left|\tan^{-1} \left( \frac{y_1}{x_1}  \right) - \tan^{-1} \left( \frac{y_2}{x_2} \right) \right| \right)[/jsTex]

Use the jsTex bbcode!

That looks super fricking complicated.

Thank you, I'll have a pop at that.

Jane's a boss, I hope the angry globuralists didn't chase her off, I enjoyed her posts.

Since when do FE'ers use mathematical formulas?

Since the beginning of time, thank you very much.

Do you have any evidence to support your outlandish claim?  I've been here for more years than I care to admit and have yet to see any FE'er put forth any workable formulas or equations that support FET.

Please check the FAQ and use the search utility. There are tremendous volumes of this type of content in the FAQ, from referenced publications, and included in quality posts from users like Tom Bishop, TheEngineer, and myself.

I've seen John Davis use some pretty high level maths. jroa is an electrical engineer so he can use math properly. Also seen ski use maths (you can't ague that he doesn't understand orthodox science.)

I doubt nark could count the fingers on his hand however.
