Then one solves the depressed cubic Depressing the cubic equation This trick, which transforms the general cubic equation into a new cubic equation with missing x 2term is due to Nicolò Fontana Tartaglia () We apply the substitutionFree equations calculator solve linear, quadratic, polynomial, radical, exponential and logarithmic equations with all the steps Type in any equation to get the solution, steps and graphThe curve with equation y = x2 cos has stationary point at x = p in the interval 0 < x < π i) Show that p satisfies the equation tan = 3 ii) Verify by calculation that p lies between 2 and 25 2 iii) Use the iterative formula p n1 = 2 tan 1 ( ) to determine the value of p correct
The solution proceeds in two steps First, the cubic equation is "depressed"; x 3 x 2 yxy 2 x 2 yxy 2 y 3 So to factorize x 3 y 3 you would need to know that you have to add and subtract x 2 y and xy 2 from the expression and factorize from there The geometric technique I mentioned helps you do this without having to guess, it quickly shows you what you must add and subtract in order to factorize the expression Section 35 Lagrange Multipliers In the previous section we optimized (ie found the absolute extrema) a function on a region that contained its boundaryFinding potential optimal points in the interior of the region isn't too bad in general, all that we needed to do was find the critical points and plug them into the function
