For an autonomous system the set of equilibrium points is equal to the set of real solutions of the equation f(x) = 0. x_ = x2: isolated equilibrium point x_ = sin(x): in nitely many equilibrium pointsThe value of x will be 1/2. Solution - To solve the equation we will find the value of x. The value of x on subtraction with 1/2 should give zero. So, as we know, if we subtract two equal numbers, the result is always zero. In those two equal numbers, one should have positive sign and other should have negative sign.
