Introduction to Trigonometry for General Studies

Learn about the application of trigonometry from measuring angles to trigonometric identities in this free online course

Publisher: ADU
Trigonometry is the branch of mathematics that studies the relationship between the lengths of the sides in a triangle. Fluency in trigonometry is necessary for studying other advanced courses in mathematics such as pre-calculus and calculus and in science courses such as physics. This free online course will give you a comprehensive understanding of various rules and concepts for getting started with solving problems in trigonometry.

Introduction to trigonometry for general studies is a free online course that has been specially prepared to take you through an introductory level of the rules, concepts and applications of trigonometry. This course begins by taking you through the use of scientific calculators. Trigonometry as the name may suggest is about right-angled triangles and is said to be the most important mathematical relationship ever discovered. It is an important tool for evaluating measurements of height and distance. Trigonometry is not narrowed to a career path or profession as it plays an important role in surveying, navigation, engineering, astronomy, computer-generated imagery and many other branches of physical science. What are trigonometric functions? Remembering trigonometric functions can be difficult and confusing. However, this course will make your learning process easier. This course covers in detail the three basic functions in trigonometry, where each is one side of a right-angled triangle divided by another. This course also explores reciprocal trigonometric functions; cosecant, secant and cotangent. This course will prepare you for basic real-life problems that can be solved using trigonometry. It will take you through illustrations that show the step-by-step procedures on how to complete different types of problems in trigonometry.

If you want to learn about special right-angle triangles, similar triangles and the methods for proving similar triangles, it is important that you complete this course. While working with trigonometry, it is also important to understand how to solve triangles using trig ratio. Trigonometry may not have many everyday applications, but it does help you to work with triangles more readily. In this course, you will learn about the measurement of angles as well as how to convert between degrees and radians. You will also learn how to determine the length of the arc of a circle. This course illustrates quadrants and angle classification. What are coterminal angles and how are they determined? This course answers frequently asked questions in trigonometry with detailed illustrations or media contents. You will learn about reference or related angle and the formulae for finding the reference angle when the terminal ray of the angle lies in quadrants II, III and IV. You will also learn about cofunctions and trigonometric values of quadrantal angles.

Furthermore, this course outlines the angle of elevation and depression as well as the line of sight. If you want to learn about the three Pythagorean identities and how to implement them, then this course is for you. Trigonometry is a useful supplement to geometry and actual measurements, and as such is worth developing an understanding of the basics. This course will take you through determining the trig value of any angle measure. You will learn about the method for finding the values of the trigonometric functions using a special property called the even and odd properties. This course explores how to find the remaining trigonometric values when one value is known. It is important for you to complete this course in order to avoid having certain concepts of trigonometry appear like a mirage. The learning contents in this course is crucial and will be of great interest to students, researchers, land surveyors or anyone with an interest in excellent working knowledge of trigonometry. So, register for this course and start your next learning journey.
