derivative of y=2-x

derivative of

y = 2 - x

- 1

Solution steps

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

Apply the Sum/Difference Rule:

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

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

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

\frac{d x}{d x} = 1

= 0 - 1

Simplify

= - 1

y^{^{''}} - y^{^{'}} + 5 y = 3

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

y^{^{''}} + 4 y = x^{2} + 3 e^{x}

\frac{\partial}{\partial x} (cos (k x))

(- 4, 3), (- 1, - 6)
