Example of Derivative of Function of Constant Multiple
- $\map {\dfrac \d {\d x} } {\map \sec {a x + b} } = a \map \sec {a x + b} \map \tan {a x + b}$
Proof
\(\ds \map {\dfrac \d {\d x} } {\map \sec {a x + b} }\) | \(=\) | \(\ds a \map {\dfrac \d {\map \d {a x + b} } } {\map \sec {a x + b} }\) | Derivative of Function of Constant Multiple: Corollary | |||||||||||
\(\ds \) | \(=\) | \(\ds a \map \sec {a x + b} \map \tan {a x + b}\) | Derivative of Secant Function |
$\blacksquare$
