Answer:
Chain rule in differentiation means .....
i m taking an e.g.
1) y= sin (ax+b)
dy/dx =?
in this , firstly we will the differentiation of sin which is cos and then do the diff. of other quantity.
ans.
dy/dx=cos(ax+b). d/dx(ax+b)
2)y=e^ax+b
dy/dx=?
in this firstly will do the differentiation of e , but its diff. is always same.
ans.
dy/dx=e^ax+b. d/dx(ax+b)
this is chain rule.
