Successive Differentiation and Study of Special Mathematical Formulas

Welcome and Introduction

• Share experiences of 2022 and describe how it felt.
• Purpose of the channel: To teach everyone partial and differential calculus.

Today's Agenda

• Cover the important topic of successive differentiation.
• Include minima and maxima and their applications.
• Importance of formulas and methods to remember them.

Formulas

Essential Formulas

• Main three formulas to remember, no need for the other two.

• Main Formula:

  [ \frac{\mathit{d}}{\mathit{dx}}(x + B)^{n} = An(x + B)^{n-1} ]

• These formulas are sufficient to solve any questions.

• No need for the other two formulas.

Algebraic Function Formulas

• Mainly types of algebraic functions:
  • First: (x/A), such as:
    [ \frac{x}{x+A} ]
  • Second: [ \frac{x}{x^2 + B^2} ]
  • Third: [ \frac{x}{x^2 + Bx + C} ]
• Different types for partial fractions:
  • Establishing A, B, C for definition.
• Evaluation of values and application of formulas.

Confusion and Solutions

• Successful derivation and memory techniques.
• Prioritizing the reduction of students' confusion.

Tips

• It is important to memorize formulas to do well in university papers.
• Regular revision and practice are necessary.

Homework

• To challenge yourself, write down the formulas without looking and solve questions.

Frequently Asked Questions

• Questions on successful differentiation:
  • Steps for substituting values and finding the answer.

Conclusion

• Many questions can be solved with just one formula.
