(\partial)/(\partial t)(2/((x-3t)^2+1))

\frac{\partial}{\partial t} (\frac{2}{( x - 3 t ) ^{2} + 1})

\frac{12 ( - 3 t + x )}{( ( x - 3 t ) ^{2} + 1 ) ^{2}}

Solution steps

\frac{\partial}{\partial t} (\frac{2}{( x - 3 t ) ^{2} + 1})

Treat

x

as a constant

Take the constant out:

(a \cdot f)^{'} = a \cdot f^{'}

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

Apply exponent rule:

\frac{1}{a} = a^{- 1}

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

Apply the chain rule:

- \frac{1}{( ( x - 3 t ) ^{2} + 1 ) ^{2}} \frac{\partial}{\partial t} ((x - 3 t)^{2} + 1)

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

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

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

Simplify

2 - \frac{1}{( ( x - 3 t ) ^{2} + 1 ) ^{2}} (- 6 (- 3 t + x)) : \frac{12 ( - 3 t + x )}{( ( x - 3 t ) ^{2} + 1 ) ^{2}}

= \frac{12 ( - 3 t + x )}{( ( x - 3 t ) ^{2} + 1 ) ^{2}}

\frac{\partial}{\partial x} (x^{6} y^{8} + 7 x^{7} y)

\int x^{2} sin (x^{3} + 4) d x

x \to c lim (x)

\frac{\partial}{\partial x} (x y^{2} - x^{2} y)

y = 4 - x^{2}, y = - 3 x
