Hi I'm just practicing my trig integrals, can you tell me
if I got this right.
The answer I got is
But my book says the answer is;
I think they are the same because of the minus sign and
the fact that inside the brackets of arcsec things are
upside down but I'm not 100%.
by the picture,
and,
so the integral becomes;
Now to calculate dx, (this gets a bit nuts);
so, the integral is NOW;
We first get rid of the by using the fact that,
and this gets our integral even closer;
cleaning it up;
All thats left to get rid of is ,
Because
and,
we see that;
so,
and the original integral finally becomes:
Cleaning it up;
and this reduces to;
to get theta I'll use;
so the final answer I get is;
ergo;
There must of been some slip-up but I haven't seen it
Unless it's correct
