derivative of 2x-y

derivative of

2 x - y

2

Solution steps

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

Treat

y

as a constant

Apply the Sum/Difference Rule:

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

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

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

\frac{d y}{d x} = 0

= 2 - 0

Simplify

= 2

t \cdot lo g_{10} (2 t)

2 t^{2} e^{- t}

\frac{( x ^{2} + 1 )}{( 1 - x )}

\frac{d}{d t} (30 + 2 t)

y = 3 cos^{4} (x)
