Implicit differentiation displays extraneous x variable.
The problem is, given
y = 9*x^(1/2) - 2*y^(3/5), find dy/dx
The answer is supposed to be
dy/dx = ( 45*y^(2/5) ) / ( 10*x^(1/2)*y^(2/5)+12*x^(1/2) )
When I enter the following syntax, there is an extraneous character, (x), displayed:
y=function('y',x) temp=diff(9*x^(1/2) - 2*y^(3/5) - y) solve (temp,diff(y)) show(solve (temp,diff(y)))
Is it possible to display the answer without showing (x)?
