derivative of

\frac{1}{( r + t )}

- \frac{1}{( r + t ) ^{2}}

Solution steps

\frac{d}{d r} (\frac{1}{r + t})

Treat

t

as a constant

Apply exponent rule:

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

= \frac{d}{d r} ((r + t)^{- 1})

Apply the chain rule:

- \frac{1}{( r + t ) ^{2}} \frac{d}{d r} (r + t)

= - \frac{1}{( r + t ) ^{2}} \frac{d}{d r} (r + t)

\frac{d}{d r} (r + t) = 1

= - \frac{1}{( r + t ) ^{2}} \cdot 1

Simplify

= - \frac{1}{( r + t ) ^{2}}

\frac{1}{( 2 x )}

\frac{( 4 - x )}{sin ^{2} ( x )}

y = ((e^{2} x) + 1)^{3}

e^{2} + x

∣ x + 2 ∣ - 2
