pls help me ,I couldnt solve these q1: if y=e x+e^x+e^x+...........∞ ,then dy/dx equals q2:if x=at 2 and y=2at then (xy*d 2 y/dx 2) is equal to sir as u asked i checked both the ques , both are from the course material and are correct the ans for q1 is = y/(1-y) . sir in q2 could u pls exp how the chain rule is applied in diff. second time thank u

let y=e^x+e^x+...........∞,

then y=ex+y

now diff

  dy/dx=ex+y(1+ dy/dx)

dy/dx(1- ex+y)= ex+y

dy/dx=( ex+y)/( 1- ex+y)

dy/dx=y/(1-y)
