Differential And Integral Calculus By Feliciano And Uy Chapter 4 Portable ❲RECENT ✭❳

In many standard calculus textbooks used in the Philippines (such as Feliciano and Uy), Chapter 4 typically marks the transition from basic differentiation rules to Applications of Derivatives. This chapter is crucial as it connects abstract mathematical rules to solving real-world problems involving motion, optimization, and curve analysis.

2.3 The Constant Multiple Rule

When a variable function is multiplied by a constant coefficient, the constant remains unaffected by the differentiation process. In many standard calculus textbooks used in the

  • Theorem: If $y = c \cdot f(x)$, then $y' = c \cdot f'(x)$.
  • Significance: This allows for the differentiation of terms like $3x^2$, yielding $6x$, without complex algebraic manipulation.

4.5 Related Rates

  • Concept: Related rates problems involve finding the rate of change of one quantity in terms of the rate of change of another quantity.
  • Procedure:
    1. Define the variables and the relationship between them.
    2. Differentiate both sides of the equation with respect to time.
    3. Substitute the known rates and solve for the unknown rate.

Chapter 4: Applications of Derivatives

Based on Differential and Integral Calculus by Feliciano and Uy Theorem: If $y = c \cdot f(x)$, then $y' = c \cdot f'(x)$

4.7 Curvature

  • Definition: Curvature is a measure of how fast the curve turns at a point.
  • Formula: For a curve given by (y = f(x)), the curvature (\kappa) can be found using the formula (\kappa = \frac(1 + y'^2)^3/2).

Type C: Product/Quotient Rule with Trig

Example: ( y = x^2 \tan x )

  • Use Product Rule: ( y' = (2x)(\tan x) + (x^2)(\sec^2 x) )
  • Final: ( y' = 2x \tan x + x^2 \sec^2 x )
