Determine if the statement is always true, sometimes true, or never true.
If y is a function of x, and is also a function of t. then dy/dx = dy/dt
i think its sometimes true but i don't know why it is. am i right?, and can you please explain me y this is the case? Thank you for your time

it could be true, if x=t
But it would be a rare case...
for instance, x= t^2
so in general, dy/dx does not = dy/dt
it x=t, it will work out.
