What is the Derivative of root x + 1/root x?

[ad_1]

See exposition.

If you mean: ##sqrt(x)+1/sqrt(x)##

Derivative is loving by:

##1/(2sqrt(x)) - 1/(2sqrt(x^3))= (x-1) / (2x^(3/2))##

If you mean: ##sqrt(x+1)/sqrt(x)##

Derivative is loving by:

##( sqrt(x) / (2sqrt(x+1)) - (sqrt(x+1)) / (2sqrt(2)) ) / x##

##implies sqrt(x) / (2xsqrt(x+1)) - (sqrt(x+1)) / (2xsqrt(2)) =- 1/ ( 2x^(3/2)sqrt(x+1) ) ##
