Same I need that too 😢

[@dasboi8386]

Sir why did you only integrate the parametric equation for y and not follow the method of y dx/dt dt Which we normally use for parametric integration?

[@MrHassaansMathsChannel]

I replaced the y with what y is equal to... I replaced the dx/dt with what it is equal to .. and I then integrated that with respect to t.... which is exactly what u stated ... watch it again and you'll see
