FAQs on Values of Trigonometric Table Video Lecture - Crash Course: Class 10

1. What is a trigonometric table?
Ans. A trigonometric table is a mathematical table that provides the values of trigonometric functions such as sine, cosine, tangent, etc., for different angles. These tables help in quickly finding the values of trigonometric functions without the need for complex calculations.
2. How is a trigonometric table useful in Class 10?
Ans. In Class 10, trigonometric tables are essential for solving problems related to triangles and angles. By using the values from the table, students can determine the lengths of sides, find unknown angles, and solve various trigonometric equations.
3. What are the values given in a trigonometric table?
Ans. A trigonometric table provides the values of trigonometric functions, such as sine, cosine, tangent, cosecant, secant, and cotangent, for different angles. These values are usually given in degrees or radians and help in solving trigonometric problems efficiently.
4. How can one use a trigonometric table to find the sine of an angle?
Ans. To find the sine of an angle using a trigonometric table, locate the angle in the table and look for the corresponding value in the sine column. For example, if you want to find the sine of 30 degrees, find 30 in the angle column and read the corresponding value in the sine column, which is 0.5.
5. Can a calculator replace a trigonometric table?
Ans. Yes, calculators can replace trigonometric tables as they can provide accurate values of trigonometric functions for any angle. However, understanding how to use a trigonometric table is still important as it helps in developing a better understanding of trigonometry and its principles.
