\frac{d}{d θ} (\frac{5}{2 cos ( θ ) + 7 sin ( θ )})

- \frac{5 ( - 2 sin ( θ ) + 7 cos ( θ ) )}{( 2 cos ( θ ) + 7 sin ( θ ) ) ^{2}}

Solution steps

\frac{d}{d θ} (\frac{5}{2 cos ( θ ) + 7 sin ( θ )})

Take the constant out:

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

= 5 \frac{d}{d θ} (\frac{1}{2 cos ( θ ) + 7 sin ( θ )})

Apply exponent rule:

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

= 5 \frac{d}{d θ} ((2 cos (θ) + 7 sin (θ))^{- 1})

Apply the chain rule:

- \frac{1}{( 2 cos ( θ ) + 7 sin ( θ ) ) ^{2}} \frac{d}{d θ} (2 cos (θ) + 7 sin (θ))

= - \frac{1}{( 2 cos ( θ ) + 7 sin ( θ ) ) ^{2}} \frac{d}{d θ} (2 cos (θ) + 7 sin (θ))

\frac{d}{d θ} (2 cos (θ) + 7 sin (θ)) = - 2 sin (θ) + 7 cos (θ)

= 5 (- \frac{1}{( 2 cos ( θ ) + 7 sin ( θ ) ) ^{2}} (- 2 sin (θ) + 7 cos (θ)))

Simplify

5 (- \frac{1}{( 2 cos ( θ ) + 7 sin ( θ ) ) ^{2}} (- 2 sin (θ) + 7 cos (θ))) : - \frac{5 ( - 2 sin ( θ ) + 7 cos ( θ ) )}{( 2 cos ( θ ) + 7 sin ( θ ) ) ^{2}}

= - \frac{5 ( - 2 sin ( θ ) + 7 cos ( θ ) )}{( 2 cos ( θ ) + 7 sin ( θ ) ) ^{2}}
