    OK I have a question why on the first two problems after taking the derivatin of MUx you added also the y and vice versa and on the last two you didn't add the second factor near the derivative of the first?
    Thanks a lot very useful but this question came into mind.

      @@Camcrazy530 because in the first few examples he is multiplying the x and y and in the other cases (where he doesn’t use the Y) he’s adding the two. Derivative of x*y by x = y. Derivative of x+y by x is 1.

    Im sure this is wrong. Isnt marginal utility supposed to be diminishing? Wouldn't the marginal utlity be increasing in the first example?

    since the 3 is brought down already, from where does the square come on the Y

    • @EconomicsinManyLessons
      @EconomicsinManyLessons  5 років тому

      You need to subtract 1 from the exponent on Y, which gives Y^(3-1) = Y^2. I did the same thing for the exponent on X.

  • @Thebt7
    @Thebt7 10 років тому

    Why is the marginal utility for y when derived 3x^2 y^2. sorry my calculus is very bad but i could not figure it out.

    • @EconomicsinManyLessons
      @EconomicsinManyLessons  10 років тому

      U = X^2Y^3
      The partial derivative of U with respect to Y = 3X^2Y^(3-1) = 3X^2 Y^2.
      Notice that the exponent on the Y term was brought down in front and then we subtracted 1 from the exponent on Y, leaving Y raised to the 2nd power.
      Another way of doing this, which might be easier to understand, is to rewrite the utility function as U = bY^3, where b = X^2.
      The derivative of bY^3 = 3bY^2. Next, substitute X^2 for b to get your final answer: 3X^2 Y^2.

    shouldn't there be a minus sign before ur result?

    • @EconomicsinManyLessons
      @EconomicsinManyLessons  5 років тому +2

      You would only put a minus sign in front of the MRS results if you wanted the slope function of the indifference curve.

    • @EconomicsinManyLessons
      @EconomicsinManyLessons  2 роки тому +1

      2/3 - 1 = 2/3 - 3/3 = -1/3.
      (I changed - 1 to - 3/3 to get the same denominator in the other term, 2/3).
