I need the indefinite integration of this: $$ \int \left[1 + \cos\left(K + \arctan\left(\frac{a+bx\ }{c + dx\ }\right)\right) \right] dx $$

If it helps, we can turn the form above into the following one. Either you can solve. $$ \int \left[1 + \cos\left(K + \arccos\left(\frac{A+Bx\ }{\sqrt(x^2+Cx+D)\ }\right)\right) \right] dx $$

By $\sqrt {u}$ I mean $u^{0.5}$

Thank you, Mahdi
