08. Introduction to Trigonometry
Trigonometry is a branch of mathematics concerned with relationships between angles and side lengths of triangles. In particular, the trigonometric functions relate the angles of a right triangle with ratios of its side lengths.
09. Some Application of Trigonometry
09. Some Application of Trigonometry
Throughout history, trigonometry has been applied in areas such as geodesy, surveying, celestial mechanics, and navigation. Trigonometry is known for its many identities.
10. Circles
10. Circles
A circle is a plane figure bounded by one curved line, and such that all straight lines drawn from a certain point within it to the bounding line, are equal.
11. Areas related to circles
11. Areas related to circles
Area of circle = πr. Circumference of circle = 2πr. Length of an arc of a sector = L= (θ/360°)×2πr. Area of a sector of circle = (θ/360°)×πr.
12. Surface Area and Volumes
12. Surface Area and Volumes
Surface area is a two-dimensional measure, while volume is a three-dimensional measure. Two figures can have the same volume but different surface areas.
13. Statistics
13. Statistics
Statistics is the discipline that concerns the collection, organization, analysis, interpretation, and presentation of data. In applying statistics to a scientific, industrial, or social problem.
14. Probability
14. Probability
Probability is the branch of mathematics concerning events and numerical descriptions of how likely they are to occur. The larger the probability, the more likely an event is to occur.
