{(x + \frac{1}{x})}^{2} = x^{2} + \frac{1}{x^{2}} + 2

x^{2} = y^{3}

{(\frac{x}{y})}^{\frac{3}{2}} + {(\frac{y}{x})}^{\frac{2}{3}} = x^{\frac{1}{2}} + y^{- \frac{1}{3}}

\int \frac{x + 3}{\sqrt{(x^{2} + 2 x + 2)}} d x = \sqrt{x^{2} + 2 x + 2} + 2 log [x + 1 - {(x + 1)^{2} + 1}^{1 / 2}] .

sec ϕ + tan ϕ = x,

sin ϕ = \frac{x^{2} - 1}{x^{2} + 1}

\int \frac{x^{2} + x + 3}{(x - 2) (x + 1)} d x = x + 3 log (x - 2) - log (x + 1)
