Question 1091702
I agree with the other tutor.  Just want to add that sometimes plotting the function helps you get a quick estimate of the solution.   To do that,  you'd write  {{{ f(x) = cos(x) - x/2 }}}, then plot f(x) and see where f(x) = 0:
—
{{{ graph(300,300, -10,10,-10,10,cos(x)-x/2) }}}
—
Zooming in on the region near x=1:
{{{ graph(400,400,-1,2,-1.5,1.5,cos(x)-x/2) }}}
