Differentiate the following functions from first principles :

We have to find the derivative of e^√2^x with the first principle method, so,

f(x) = e^√^2x

by using the first principle formula, we get,

f ‘(x) =

[By using = 1]

f ‘(x) =

[By rationalising]

f ‘(x) =

Differentiate the following functions from first principles :

e^{ax + b}
