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.This x-intercept will typically be a better approximation to the function's root than the original guess, and the method can be iterated. Newton's method is an extremely powerful technique—in general the convergence is quadratic: as the method converges on the root, the difference between the root and the approximation is squared (the number of …All Real Numbers such that x = x 2 0 and 1 are the only cases where x = x 2.
