derivative of

y - 7 y

\frac{1}{2 y} - 7

Solution steps

\frac{d}{d y} (y - 7 y)

Apply the Sum/Difference Rule:

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

= \frac{d}{d y} (y) - \frac{d}{d y} (7 y)

\frac{d}{d y} (y) = \frac{1}{2 y}

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

= \frac{1}{2 y} - 7

\frac{\partial}{\partial y} (3 x^{5} tan (y) - 2 y^{3})

\int_{1.5}^{2} cos (\frac{π x}{3}) d x

y^{^{'}} + y t = 6 cos (5 t)

sin (9 x)

\frac{d}{d x} ((a + \frac{b}{x ^{2}})^{3})
