derivative of 2-7x

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

- 7

Solution steps

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

Apply the Sum/Difference Rule:

(f \pm g)^{'} = f^{'} \pm g^{'}

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

\frac{d}{d x} (2) = 0

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

= 0 - 7

Simplify

= - 7

\frac{d}{d x} (\frac{sin ^{2} ( x )}{sin ( x ^{2} )})

\int_{0}^{π} sec (x) d x

\int cos (x) \cdot sin^{3} (x) d x

\int_{0}^{1} \frac{- 7 y}{e ^{2 y}} d y

e^{- 10 t}
