Solve w=p-2l/2 - ScanMath

Evaluate

w = p - (2 \times \frac{l}{2})

Multiply the terms

More Steps

w = p - l

Find the first partial derivative by treating the variable l as a constant and differentiating with respect to p

\frac{\partial w}{\partial p} = \frac{\partial}{\partial p} (p - l)

Use differentiation rule \frac{\partial}{\partial x} (f (x) \pm g (x)) = \frac{\partial}{\partial x} (f (x)) \pm \frac{\partial}{\partial x} (g (x))

\frac{\partial w}{\partial p} = \frac{\partial}{\partial p} (p) - \frac{\partial}{\partial p} (l)

Use \frac{\partial}{\partial x} x^{n} = n x^{n - 1} to find derivative

\frac{\partial w}{\partial p} = 1 - \frac{\partial}{\partial p} (l)

Use \frac{\partial}{\partial x} (c) = 0 to find derivative

\frac{\partial w}{\partial p} = 1 - 0

Solution

\frac{\partial w}{\partial p} = 1
