We can solve the integral $\int\frac{1}{\cos\left(x\right)+\sin\left(x\right)+1}dx$ by applying the method Weierstrass substitution (also known as tangent half-angle substitution) which converts an integral of trigonometric functions into a rational function of $t$ by setting the substitution

$t=\tan\left(\frac{x}{2}\right)$
