ln (a) r i t m os \frac{( 2 x + 1 ) ( 3 x - 1 )}{4 x + 3}

i \frac{6 x ^{2} + x - 1}{4 x + 3} r t m os ln (a)

求解步骤

ln (a) r i t m os \frac{( 2 x + 1 ) ( 3 x - 1 )}{4 x + 3}

\frac{( 2 x + 1 ) ( 3 x - 1 )}{4 x + 3} = \frac{6 x ^{2} + x - 1}{4 x + 3}

= i \frac{6 x ^{2} + x - 1}{4 x + 3} r t m os ln (a)

e x p an d e^{θ} (sin (θ) + cos (θ))

e x p an d e^{x} ln (e^{x} + 1) - e^{- x} (e^{x} + 1)

e x p an d - \frac{2 ( e ^{x} - e ^{- x} )}{( e ^{x} + e ^{- x} ) ^{2}}

e x p an d r \cdot w \cdot (1 - cos (w \cdot t), sin (w \cdot t))

e x p an d \frac{( y + 1 ) ^{2}}{x}
