    Hey Prof. Dave just a suggestion: what if every 5-10 clips you had a small review quiz of 10-15 questions. It would help with further comprehension as well as retention of material for your students.

    I just got an advert saying "still searching UA-cam for maths help? Are the videos from 2006 really helping?". If only they knew...

    Read the definition in Wikipedia and compared it with yours. Yours is way much clearer. I just admire the quality of your explanations and videos in general. Super professional!

    Hey Prof.Dave i am a boy from india ...yes your heard it right IINNDDIIAA ,Now just don't judge me that i am a indian so i am good in maths ,Unfortunately i am not but i always wanna be too good in maths ,and i have decided to attend an examination i.e, JEE Mains + JEE advance, I do have 3years so that exam but i just want to know from where i should start it or i should study...

    What does the sub N part mean?

      A little explanation of the beginning part with the subscripts would help clarify the rest of the video.

      Those are subscripts. They are there to show a possible template of the polynomial. n can be any number here example in the quadratic polynomial 2x^2 + 3x +7 , n is 2 .consider it like this x^0 then n= 0 , x^1 then n= 1, when x^n then n= n, n is just a figure to represent any number which is the highest power of the variable in that equation. the subscript just denotes the count of expressions ex: 2x + b has 2 expression surrounding the +, the 2x and the b , so b is the 0th element and 2 the 1st element. Which conveniently also happens to be the power of the variable of the respective coefficients.

    • @NickHope
      @NickHope 3 роки тому +7

      I guess those subscripts are just like labels attached to the preceding character, and we don't do any mathematical operation with them.
      'a' is not the same in each part of the polynomial, but instead of writing 'a', 'b', 'c' etc., he writes, for example, 'a sub (n-1)', meaning "the factor 'a' that belongs in the part of the polynomial where x is raised to the power (n-1)."
      Likewise, 'a sub (n-3)' means "the factor 'a' that belongs in the part of the polynomial where x is raised to the power (n-3)."
      I might be wrong. I wish Dave had explained what they are rather than just throw them in there. It's the first time this brilliant course has me lost.

    2x^2+4x+10
    2(-1)^2+4(-1)+10
    2-4+10-----USE PEMDAS
    =12 is the correct answer

      I think you might wanna go back to the first videos of this series in the arithmetic section and learn from scratch of how precedence property for an equation or expression in general works princess.
      Here's a tip: polarity of a number is always conserved for any precedence property or rule.

    Hi Prof Dave!
    I am confused regarding the real life application of the polynomials.
    What kind of real life problem involves modelling by using higher exponents of the same variable, x and then slowly decreasing them forming a polynomial?

      Hey there,
      Real-life applications of polynomials are more common than you might think. Let's break it down:
      **1. Physics:** When you throw a ball into the air, its height can be modeled by a polynomial function. The equation includes terms for gravity (a constant) and the initial velocity of the ball.
      **2. Engineering:** Structural engineers use polynomial equations to design bridges, buildings, and other structures. These equations help predict factors like stress, strain, and load distribution.
      **3. Economics:** In finance, polynomial functions are used to model things like supply and demand curves, cost functions, and revenue functions. This helps businesses optimize their operations and maximize profits.
      **4. Medicine:** Polynomial equations are used in medical research to model things like growth rates of tumors, drug absorption rates, and population growth of diseases.
      **5. Computer Graphics:** Graphics software uses polynomial equations to render 3D objects and animations. These equations help determine the shape, position, and movement of objects on the screen.
      So, whether you're calculating the trajectory of a rocket, designing a skyscraper, or analyzing market trends, polynomials are there, quietly doing the heavy lifting behind the scenes.
      Hope that clears things up for you!
