Solve h = l/n - ScanMath

Simplify

h = \frac{l}{n}

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

\frac{\partial h}{\partial l} = \frac{\partial}{\partial l} (\frac{l}{n})

Use differentiation rule \frac{\partial}{\partial x} (\frac{f ( x )}{g ( x )}) = \frac{\frac{\partial}{\partial x} ( f ( x )) \times g ( x ) - f ( x ) \times \frac{\partial}{\partial x} ( g ( x ) )}{( g ( x ) ) ^{2}}

\frac{\partial h}{\partial l} = \frac{\frac{\partial}{\partial l} ( l ) n - l \times \frac{\partial}{\partial l} ( n )}{n ^{2}}

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

\frac{\partial h}{\partial l} = \frac{1 \times n - l \times \frac{\partial}{\partial l} ( n )}{n ^{2}}

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

\frac{\partial h}{\partial l} = \frac{1 \times n - l \times 0}{n ^{2}}

Any expression multiplied by 1 remains the same

\frac{\partial h}{\partial l} = \frac{n - l \times 0}{n ^{2}}

Any expression multiplied by 0 equals 0

\frac{\partial h}{\partial l} = \frac{n - 0}{n ^{2}}

Removing 0 doesn't change the value,so remove it from the expression

\frac{\partial h}{\partial l} = \frac{n}{n ^{2}}
