About the author

Marge Lial (late) was always interested in math; it was her favorite subject in the first grade! Her desire to educate both her students and herself inspired the writing of numerous best-selling textbooks. Marge, who received Bachelor's and Master's degrees from California State University at Sacramento, was most recently affiliated with American River College. An avid reader and traveler, Marge’s travel experiences often find their way into her books as applications, exercise sets, and feature sets. She was particularly interested in archeology. Trips to various digs and ruin sites produced some fascinating problems for her textbooks, involving such topics as the building of Mayan pyramids and the acoustics of ancient ball courts in the Yucatan.

[Melissa Brogan · Rating 3 out of 5]

At times, more useful than my professor. Chapter on identities could use some work, though; things were a little unclear.

Trigonometry is SO fulfilling! (Or math in general for that matter)

Not terrible, good I guess for a trigonometry book. If you're stuck taking this class be prepared for lists upon lists of formulas to memorize.

that will make you want to:

until your

YIPPEE it's over!!!
