Hello sir im not able to solve eqn which we got after partial diff And also When 2 conditions given in quest but they don’t give function n ask distance Or say volume of parallelopiped in ellipse etc Im getting confused Bcz I don’t know what function i have to take They used x^2 + y^2 +z^2. As function how And when they asked distance btw origin n any parellelo etc They use x^2 +y2. As fn

To know that the point is maximum we put that point in function and find its value. Then we take any random point which also lie on that function restricted by constraints and find its value of function and compare the function values if in first case we got the point having maximum value of function then function values of all other points is less than the function value of that point.

If you get only one point then yes :)

by langrange method we get local extreme values or global extreme value? if we got single pt then how to decide whether it is maxima or minima?
@DrMathaholic

Well, It gives local extreme values bt if your constraints satisfies some good conditions ( you might study in future if u opt advanced optimization subject) then those local implies global. Wel, the method is so nice that the point you find will give you wat your problem asks 😀😀 Lot of things to say, if interested pls see this: math.stackexchange.com/questions/2076766/how-to-know-whether-lagrange-multipliers-gives-maximum-or-minimum

Langranges method is applicable only for boundry points for finding maxima or minima? Does we have to solve separately for interior points?
@DrMathaholic

Yes. For interior points, we do partial differentiation and equate it to 0. But at boundary we don't do differentiation so that's where Lagrange multiplier method comes to our rescue...
