FAQs on Introduction to Trigonometric Functions Video Lecture - Mathematics (Maths) Class 11 - Commerce

1. What are trigonometric functions?
Ans. Trigonometric functions are mathematical functions that relate angles of a triangle to the ratios of the sides of the triangle. They are used to solve various problems in geometry, physics, and engineering.
2. What are the six trigonometric functions?
Ans. The six trigonometric functions are sine (sin), cosine (cos), tangent (tan), cosecant (csc), secant (sec), and cotangent (cot). Each function represents a ratio of two sides of a right triangle.
3. How are trigonometric functions used in real life?
Ans. Trigonometric functions are used in various real-life applications, such as navigation, architecture, surveying, and physics. They help in determining distances, angles, heights, and other measurements.
4. What is the unit circle and its relation to trigonometric functions?
Ans. The unit circle is a circle with a radius of 1 unit. It is used to define the values of trigonometric functions for any angle. The coordinates of a point on the unit circle represent the values of sine and cosine for that angle.
5. How can I use trigonometric functions to solve problems involving right triangles?
Ans. Trigonometric functions can be used to solve problems involving right triangles by utilizing the ratios of their sides. By knowing the lengths of two sides, or one side and one angle, you can use the appropriate trigonometric function to find the missing values.
