Question

all formula of differentiations

Answer 1

Welli cannot speak for all the most important ones are : 

d(x)/dx = 1
d(x^n)/dx = nx^(n-1)
d(sinx)/dx = cos x
d(cos x)/dx = -sin x
d(tanx)/dx = sec^2x 
d(secx)/dx = tanx secx 
d(cotx)/dx = -cosec^2x 
d (cosec x)/dx = -cosec x cotx 
d (ln x) = 1/x
d $\sqrt{x}$ = 1/2$\sqrt{x}$

There are many more but these are the most useful ones
