# Essentials of College Algebra with Modeling and by Gary K. Rockswold

By Gary K. Rockswold

Gary Rockswold teaches algebra in context, answering the query, “Why am I studying this?” through experiencing math via functions, scholars see the way it matches into their lives, they usually turn into stimulated to be successful. Rockswold’s concentrate on conceptual realizing is helping scholars make connections among the techniques and therefore, scholars see the larger photograph of math and are ready for destiny classes. This streamlined textual content covers linear, quadratic, nonlinear, exponential, and logarithmic services and structures of equations and inequalities, which will get to the center of what scholars desire from this path. A extra entire university algebra textual content is usually on hand.

Polynomial root-finding and polynomiography

This ebook bargains attention-grabbing and sleek views into the idea and perform of the ancient topic of polynomial root-finding, rejuvenating the sphere through polynomiography, an artistic and novel computing device visualization that renders outstanding photographs of a polynomial equation. Polynomiography won't in simple terms pave the best way for brand spanking new functions of polynomials in technology and arithmetic, but in addition in paintings and schooling.
