Answer 1

Answer:

2

Step-by-step explanation:

differentiation of e^x is e^x itself.

And for differentiation of other term, you have to use chain rule. Means keep x constant and differentiate cosx and in other turn keep cosx constant and differentiate x.

So, final differentiation answer is,

-xsinx + cosx + e^x

On putting x = 0,

sinx =0, cosx = 1 and e^x = 1.

So, answer is 2.
