\frac{d}{d x} (arcsin (7 x))

\frac{7}{1 - 49 x ^{2}}

Solution steps

\frac{d}{d x} (arcsin (7 x))

Apply the chain rule:

\frac{1}{1 - ( 7 x ) ^{2}} \frac{d}{d x} (7 x)

= \frac{1}{1 - ( 7 x ) ^{2}} \frac{d}{d x} (7 x)

\frac{d}{d x} (7 x) = 7

= \frac{1}{1 - ( 7 x ) ^{2}} \cdot 7

Simplify

\frac{1}{1 - ( 7 x ) ^{2}} \cdot 7 : \frac{7}{1 - 49 x ^{2}}

= \frac{7}{1 - 49 x ^{2}}
