is a constant. so for just use the power rule to differentiate it. as for its derivative is itself.

i suppose you are talking in the context of implicit differentiation?also, what is the difference between (d/dt) and (d/dx). I found on (d/dt) that I can solve normally, however (d/dx) asks for a different answer?

anyway, the notation is interpreted thus: mean you are taking the derivative with respect to . an analogous interpretation holds for

example:

differentiate implicitly with respect to

so we have

(we put dx/dx to say we took the "derivative of an x-term with respect to x" and dy/dx to say we took the "derivative of a y-term with respect to x")

if we differentiated the same equation with respect to we would get

(we put dx/dt to say we took the "derivative of an x-term with respect to t" and dy/dt to say we took the "derivative of a y-term with respect to t")

see the difference?
