Major topics discussed in CBSE Class 10 Maths Chapter – Introduction to Trigonometry include:

1.Trigonometry is the branch of Mathematics which deals with the measurement of sides and angles of the triangles.

2.In a right triangle ABC, right-angled at B,

• sin A = side opposite to angle A/hypotenuse
• cos A = side adjacent to angle A/ hypotenuse
• tan A = side adjacent to angle A/side opposite to angle A
• cosec A =1/sinA
• sec A = 1/cosA
• tan A = 1/cotA
• tan A = sinA/cosA

3.If one of the trigonometric ratios of an acute angle is known, the remaining trigonometric ratios of the angle can be easily determined.

4.The values of trigonometric ratios for angles 0°, 30°, 45°, 60° and 90°.

5.The value of sin A or cos A never exceeds 1, whereas the value of sec A or cosec A is always greater than or equal to 1.

6.sin²A + cos²A = 1,

sec²A – tan²A = 1  for  0° ≤ A ≤ 90°

cosec²A = 1 + cot²A  for  0° < A ≤ 90^o.
