Enter the function f(x) = sin(x) / x. Search for roots and/or extrema on the interval [0,10]. Once the graph appears, click on the lowest point on the curve to find the minimun value of the function.
Enter the function f(x) = cos(x) - x. Search for roots on the interval [0,1]. Once the graph appears, click on the point where the graph crosses the x-axis.
