Prove 2n^3 - 7n + 1 is Ω(n^3) - Big Omega Example
In this video, I will show you how to prove or disprove Big Omega Ω. For example, you are asked to prove that a function 2n^3 - 7n + 1 is Ω(n^3). By the definition of big O, f(n) is O(g(n)) if you can find a positive constant c and a positive integer nₒ such that f(n) is less than or equal to c times g(n), for all n is greater than nₒ. By the definition of big Omega, f(n) is Ω(g(n)) if f(n) is greater than or equal to c*g(n)
Knowing how to prove that something is Big O or not Big O is an important skill that Computer Science CS and Math students need to know about time complexity and growth of functions. It is likely that you will encounter this topic in your typical Data Structures, Discrete Mathematics, or Analysis of Algorithm courses at University.
I will also how you how to prive Big Omega Ω or Big Theta θ. If you enjoyed this video, please don't forget to comment down below and also subscribe if you haven't already!

In this video, I will show you how to solve the indefinite integral of sin(3x) using u substitution. This is an important topic for students taking Calculus, whether it is AP Calculus or Calculus in university. The idea behind u-substitution is to simply the integrand. For example, we can simplify 1/(2x 4) with 1/u where u=2x 4. The second step is to differentiate u with respect to x, then plug...

In this video, I will explain stacks often taught in a data structures and algorithms course. Stacks can be implemented with an array or a linked list. If a stack is implemented by an array, it is called an ArrayStack. But if the stack is implemented by a linked list, then it is called a LinkedStack. Stacks have a special property called FILO, or First in Last Out. I show plenty of examples in ...

In this video, I will show you the proof or derivation of the quadratic formula. The quadratic equation is ax^2 bx c = 0, where a != 0. If you want to solve for x, the formula is x = (-b - sqrt(b^2 - 4ac))/2a. In this video, I will show you how to prove the quadratic formula or show you how to derive the quadratic formula. You will need to complete the square. This is a useful topic that math s...

    If you do not mind me asking, what is the reason behind splitting up the integral in the last example???

    • @QuocDatPhung
      @QuocDatPhung 21 день тому

      There's a vertical asymptote at x = 1, meaning when x = 1, the function has divide by 0. This is why you split the integral up, and you get from x=0 to x=1 and x=1 to x=3. Let me know if that makes sense!
