# SECTION 2: COORDINATE GEOMETRY, VECTORS AND TRIGONOMETRY

## Cover Section 2 for CSEC Additional Mathematics syllabus.

At the end of this section, students should be able to:

• evaluate sine, cosine and tangent for angles of any size given either in degrees or radians;
• evaluate the exact values of sine, cosine and tangent
• graph the functions of sine, cosine and tangent
• derive the Pythagorean Identity $\sin^2{\theta}+\cos^2{\theta}=1$
• use the compound angle formulae;
• derive the double angle FORMULAE;
• solve simple identities;
• find solutions of simple equations for a given range.

Sean Hunte, Your Passionate Mathematics Teacher

I was once a student just like you. I struggled with Mathematics for the first two (2) years of my secondary school life. In third form my teacher, Dr Sargeant, taught Mathematics in a unique way which allowed me to successfully learn the subject which I was passionate about. Her teaching enabled me to thrive in an area which I would eventually pursue as a career.

Therefore, I have successfully completed CXC's CSEC General Mathematics and CAPE Pure Mathematics Units 1 and 2 before obtaining a degree in Economics and Mathematics.

I have ten (10) years of experience teaching Mathematics at the secondary level in Barbados. During this time I have taught hundreds of students who have successfully completed the following courses:

• CSEC GENERAL MATHEMATICS
• CAPE PURE MATHEMATICS UNIT 1
• CAPE PURE MATHEMATICS UNIT 2
• SAT MATHEMATICS

Your story will be different from mine but both of us desire the same result. SUCCESS!

I know that for many students Mathematics can be a struggle. I am therefore here to offer assistance in making the learning of Mathematics easier.
