Solve b = l n - 1

Simplify

b = l n - 1

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

\frac{\partial b}{\partial l} = \frac{\partial}{\partial l} (l n - 1)

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 b}{\partial l} = \frac{\partial}{\partial l} (l n) - \frac{\partial}{\partial l} (1)

Evaluate

More Steps

\frac{\partial b}{\partial l} = n - \frac{\partial}{\partial l} (1)

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

\frac{\partial b}{\partial l} = n - 0

Solution

\frac{\partial b}{\partial l} = n
