Is y = y(x,t) ?
if we implicitly differentiate
is this the right approach?
which means (I intend it to mean)
the derivative of y with respect to itself TIMES the derivative of y with respect to x MINUS [the derivative of x with respect to itself times y^2 PLUS the derivative of y with respect to itself TIMES x]
firstly did I write in math what I wrote in english? and secondly is it correct?
thanks!
