I need help with radians.. One of my questions is: An angle of 0 (with line through it) =249 degrees is equivalent to how many radians? Answer in units of rad.
Thanks!

1 degree = [itex]\pi[/itex]/180 radians. Angle [itex]\theta[/itex] = 249 degrees. What do you think you should do?

Would the answer be 4.35 radians?

Yes, but that would be an approximation.

[tex]249^\circ = \frac{{249\pi }}{{180}}rad = \frac{{83\pi }}{{60}}rad \approx 4.35rad[/tex]

That's what I get, if you're rounding.

I forgot you got to be fast around here. :biggrin:

Just a really, really, really small point. Radians, I am sure, can be written as [tex]\pi ^c[/tex].

Like I said - a really, realy, really small point.

I never knew that, in my books, they always denoted radians by putting a little R superscript, like so:

[itex]2\pi^R[/itex]

Really? I usually use c. I have never seen that before. I expected to R when I studied radians but we use c.
