If xy-5=x^3/2 determine dy/dx.
If xy-5=x^3/2 determine dy/dx.
Solution
For xy - 5 = x^(3/2) the value of dy/dx can be found using implicit differentiation.
x*dy/dx + y - 0 = (3/2)*x^(1/2)
=> dy/dx = ((3/2)*x^(1/2) - y)/x
xy - 5 = x^(3/2)
=> y = (x^(3/2) + 5)/x
dy/dx = ((3/2)*x^(1/2) - (x^(3/2) + 5)/x)/x
The required derivative dy/dx = ((3/2)*x^(1/2) - (x^(3/2) + 5)/x)/x
