I'm having trouble integrating this arc length.

General formula:

, between intervalsaandb

My function: , where a=0.00183

So

Putting this derivative into general formula:

, between the intervals of176.3and-176.3. (I haven't put a=0.00183 in yet because it would get too messy intergrating it.)

I don't know how to integrate this because I think it involves some method of substitution which I don't know. Any help would be great ;D
