A B 3 Formula Derivation

First i note that they ve given me a binomial a two term polynomial and that the power on the x in the first term is 3 so even if i weren t working in the sums and differences of cubes section of my textbook i d be on notice that maybe i should be thinking in terms of those formulas.

A b 3 formula derivation. A 1 b n 2 b n 1 exponent law view a a 1 2. F x 3x 2 2 5x 1 0 3x 2 10x 1 example 2. A 3 b 3 formula a b 2 a b c 2 a b 3 a 3 3a 2b 3ab 2 b 3 a 3 b 3 a b a 2 ab b 2 home maths formulas. F x x 3 5x 2 x 8.

These all are easily derived from one and another. Looking at the other variable i note that a power of 6 is the cube of a power of 2 so the other. A3 3a2b 3ab2 b3. A 3 b 3 a b a 2 a b b 2.

A b 3 c 3 0 a 3 b 0 c 3 1 a 2 b 1 c 3 2 a b 2 c 3 3 a 0 b 3 notice that the exponents of a descends from 3 to 0 and the exponents of b ascends from 0 to 3. If you are a class 9 10 11 o. It s easy to prove. This formula is the general form of the leibniz integral rule and can be derived using the fundamental theorem of calculus.

When the first derivative of a function is zero at point x 0. It may help you to learn more formula. A b c 0 a 3 b 3 c 3 3abc some not so common formulas power n formula a n b n a b a n 1 a n 2 b 1 a n 3 b 2. A3 a2b 2a2b 2ab2 ab2 b3.

Try to practice it more and more and never try to learn. What is a b 3 formula. F x sin 3x 2. Then the second derivative at point x 0 f x 0 can indicate the type of that point.
