dlifferentiation the following funetiony = 3 cos x + 7e x + log (x2 + 1)

Answer»

differentiate each partdy/dx=-3sinx+7e^x+(1/x^2+1)*2xdifferentiation of cosx=-sinxe^x=e^xlogx=1/x

how can calculate it because when will differentiation of log(x^2+1)then answer

because the function inside log is not a single value functionwe then need to apply chain rule to differentiate x^2+1 too
