Informative set
Besides the good quality and beauty of the stamps in this set, it also gives information on the different kinds of typical costumes worn by the Spanish people. Tradition and History combined to open a window in the traditional garments of picturesque, contrasting, and beautiful Spain

Great book for reviewing
This edition, a teacher's edition, has allowed me to make a thorough review of all my basic knowledge in Precalculus math
The different topics are well-explained with numerous exercises with answers
Many graphs in the book , too.
I highly recommend it!!!!

Good book for refreshing college concepts
As I wrote on the title, this book is an excellent source for reviewing and refreshing the Trigonometry that we studied in college.
I highly recommend it to those who want to review or even those who need to study for the first time the basic concepts and numerous applications of this branch of Mathematics
