[tex] \int \frac{dx}{5 - 3\sin x + 4 cos x} [/tex](adsbygoogle = window.adsbygoogle || []).push({});

I know I have to use t = tan(x/2) substitution, and after i do that and symplify I get:

[tex] \int \frac{dt}{2t^2 - 3t + 1} [/tex]

I dont know where to go from here. If anyone can see where to go, please help. Also, if there is an easier way to do this, please tell me!! Thanks.
