Solve m =-8j-9k 9

Evaluate

m = - 8 j - 9 k \times 9

Multiply the terms

m = - 8 j - 81 k

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

\frac{\partial m}{\partial j} = \frac{\partial}{\partial j} (- 8 j - 81 k)

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 m}{\partial j} = - \frac{\partial}{\partial j} (8 j) - \frac{\partial}{\partial j} (81 k)

Evaluate

More Steps

\frac{\partial m}{\partial j} = - 8 - \frac{\partial}{\partial j} (81 k)

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

\frac{\partial m}{\partial j} = - 8 - 0

Solution

\frac{\partial m}{\partial j} = - 8
