Trigonometry

Hello students, I scheduled a master class on trigonometry.

When we talk about higher class trigonometry, we encounter different topics like measurement of angle, relationship between arc/radius/angle, different formula, and formula-based questions.
But before going to study this topic we need to create strong fundamentals of trigonometry.

And this is how to calculate the value of trigonometry ratio at higher angle (more than 90 degree).  We study how to calculate the value of trigonometry ratio at higher-to-higher angle.

For this we study graphs of sin and cos to understand patterns of value at different angles. We study division of quadrants and how to get an idea in which quadrant our angle lies. This is also useful to get values of different angles.

After this session you are able to find values like (sin(690⁰), tan(1050⁰) and other higher angles, you know what is the domain and range of trigonometry ratio. Also you draw the graph of all trigonometry ratios.

Since I already told you that this is a fundamental topic, you will see its uses approx. in all chapters not only of class 11 but also of class 12.
This topic is relevant to any board student.
