Re: (sin(x)+log(x)+sqrt(x))'

What, exactly, is your question? You surely know, from questions you have posted before, that the derivative of sin(x) is cos(x), the derivative of log(x) is 1/x, and the derivative of . As far as the graph is concerned, calculate those at various values of x to see what happens.
