ok we're learning the part of calc 2 where you have y = 3 + 4t; x = 4 + 3t(adsbygoogle = window.adsbygoogle || []).push({});

then u multiply dy/dt * dy/dx / dx/dt

but then u just plug in the value of t into dy/dt.... so what was the point of finding the whole second part? lol it seems random and pointless to me. my friend says when u do this t "sometimes" cancells out. seems like a lot of work for nothing
