Now it might confuse you a little bit. You're not used to seeing x as a function of a third variable or y as a function of something other than x. But remember, x and y are just variables. This could be f of t and this could be g of t instead of x of t and y of t, and that might feel a little bit more natural to you. But needless to say, if we wanna find dy dt, what we wanna do is take the derivative with respect to t of both sides of this equation. So let's do that. So we're gonna do it on the left-hand side.
