Solve u=b/h - ScanMath

Simplify

u = \frac{b}{h}

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

\frac{\partial u}{\partial b} = \frac{\partial}{\partial b} (\frac{b}{h})

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 u}{\partial b} = \frac{\frac{\partial}{\partial b} ( b ) h - b \times \frac{\partial}{\partial b} ( h )}{h ^{2}}

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

\frac{\partial u}{\partial b} = \frac{1 \times h - b \times \frac{\partial}{\partial b} ( h )}{h ^{2}}

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

\frac{\partial u}{\partial b} = \frac{1 \times h - b \times 0}{h ^{2}}

Any expression multiplied by 1 remains the same

\frac{\partial u}{\partial b} = \frac{h - b \times 0}{h ^{2}}

Any expression multiplied by 0 equals 0

\frac{\partial u}{\partial b} = \frac{h - 0}{h ^{2}}

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

\frac{\partial u}{\partial b} = \frac{h}{h ^{2}}
