I have this function: f(x):=x*sin(x^(2))+1 The function is defined in the interval [-1;3] and the diff: df := sin(x^2)+2*x^2*cos(x^2) But when I try to find out where the diff function equals 0: solve(df = 0, x)*assume-1

Hi. I have a simple problem here. I only need one result from a result list that maple gives me. As you can see below. I need the value of the variable F. But maple does not give me a single result (in this case 2), it gives me many. So how do i tell maple to give me only the first result (1.0353)? > evalf[5](solve(K = S*F^n, F));
