i want its full soln
but your answer is right
Please mark brainliest I m sending a solution
As when you apply df(x)dx=df(x)/dx into d(x)/dx
bro sahi nahi hai
Kaise?

lim h-0 sin(x+h) - sin x / h
lim h-0 2cos((x+x+h) / 2).sin ((x+h-x) / 2) / h
lim h-0 {2cos(x+h/2).sin [(h/ 2) / (h/2)]*h/2}/h as sinx / x = 1
2cosx / 2
= sinx
lim h-0 2cos((x+x+h) / 2).sin ((x+h-x) / 2) / h
lim h-0 {2cos(x+h/2).sin [(h/ 2) / (h/2)]*h/2}/h as sinx / x = 1
2cosx / 2
= sinx
