Feliciano and Uy’s textbook is highly regarded because of its unique pedagogical approach, which is fully on display in Chapter 4:

Applying the chain rule to f(x) = ln u , we get:

A straight line perpendicular to the tangent line at the point of tangency. Key Formulas Slope of the Tangent ( ): Evaluated using the first derivative of the function at

Chapter 4 typically breaks down into several key areas. Here are the core topics you will find:

v(t)=dsdtv open paren t close paren equals d s over d t end-fraction

This chapter shifts the focus from polynomials, roots, and quotients of

and solving for the unknown rate (e.g.,

Derivatives for the other hyperbolic functions follow a pattern similar to their trigonometric counterparts, with one key difference: d/dx (cosh x) = +sinh x , whereas its trigonometric cousin yields -sin x . This subtle distinction is a common source of errors for students.

By mastering the concepts in Chapter 4, readers will gain a solid understanding of differentiation and be well-prepared to tackle more advanced topics in calculus.

This is the workhorse of calculus differentiation. Feliciano and Uy present this as a generalization applicable to any real number exponent.
