ABSTRACT

Step By Step Guide to using Scientific Calculator Casio fx-570MS for
Polytechnic Students first edition written for diploma students studying in
polytechnic institutions. This e-book is designed to shown step by step how to
use the Calculator Casio fx-570MS for chapters covered in the Engineering
Mathematics 1 (DBM 10013) syllabus which are Basic Algebra, Trigonometry,
Complex Number, Matrices and Vector And Scalar. This e-book also can reduce
students' mistakes and negligence in using scientific calculator while
answering mathematic questions. This book also been designed to help
students to increase students' knowledge in the use of scientific calculator and
students can master the techniques of using scientific calculators correctly.
Aside from that, the concepts, methods and notes are represented conveniently
by using simple words. Drill and practice Exercises Questions are provided to
help students expand the understanding in using scientific calculators for
beyond teaching.
