Question

Differenciate with respect to x and Check it is write or wrong f(x) = Sinx + Cosx + logx ?No spam ​

Answer 1

Answer:

we have

         f (x) = Sin x + Cos (x) + log x

Step-by-step explanation:

hence ,

          df(x) / dx = Cos x - Sin x + 1 /x        ........(1)

so your answer is 1

I hope it helps.

Answer 2

Given

f(x) = sinx + cosx + logx

differentiating with respect to X we get

f'(X) = cosx - sinx + 1/X

we know that integration is the reverse process of differentiation

So

$\int( \sin(x) + \cos(x) + log(x) )dx$

After intigration

- cosx + sinx + 1/x + c

The result is similar to f(x) so proved
