Statement 1: $\int \frac{\left\{f\left(x\right){\phi }^{prime}\left(x\right)-f^{prime}\left(x\right)\phi \left(x\right)\right\}}{f\left(x\right)\phi \left(x\right)}$$-\log f\left(x\right)dx=\frac{1}{2}{\left\{\frac{\phi \left(x\right)}{f\left(x\right)}\right\}}^2+c$ Statement 2 : $\int {\left(h\left(x\right)\right)}^n{h}^{prime}\left(x\right)dx=\frac{{\left(h\left(x\right)\right)}^{n+1}}{n+1}+c$
