 +====== Unit 07: Introduction to Trigonometry ====== 
 + 
 +After studying this unit, the students will be able to: 
 +  * measure an angle in degree, minutes and second. 
 +  * convert an angle given in degrees, minutes and seconds into decimal form and vice versa. 
 +  * define a radian (measure of an angle in circular system) and prove the relation between radians and degree. 
 +  * establish the rule $l=r\theta$, where $r$ is the radius of the circle, $l$ is length of circular arc and $\theta$ the central angel measured in radian. 
 +  * prove that the area of a sector of a circle is $\frac{1}{2}r^2 \theta$
