00:04 CBSE class 10 maths NCERT Solutions Trigonometry Exercise 8.1 Q1. In triangle ABC, right-angled at B, AB = 24 cm, BC = 7 cm. Determine
(i) sin A, cos A 003:00 (ii) sin C, cos C
00:25 Naming the sides | Finding sides of right triangle.
00:45 Pythagoras Theorem
01:40 Trigonometric Ratio Defination
sine of angle theta = side opposite to angle theta / hypotenuse
sin is equal to opposite over hypotenuse.
Remember as ' SOH '
02:15 cosine of angle theta = side adjacent to angle theta / hypotenuse
Remember as ' CAH ' Cosine equals Adjacent over Hypotenus.

03:54 CBSE class 10 maths NCERT Solutions Trigonometry Exercise 8.1 Q2. In Fig. 8.13, find tan P – cot R.
04:08 Finding the sides of right triangle
04:31 Pythagoras Theorem
05:30 Tangent of angle theta = side opposite to angle theta / side adjacent to angle theta.Remeber as ' TAO '. Tan is adjacent over
06:18 cotangent of angle theta = side adjacent to angle theta / side opposite to angle theta

07:14 CBSE class 10 maths NCERT Solutions Trigonometry Exercise 8.1 Q3. If sin A = 3/4 calculate cos A and tan A.
07:47 Finding the sides of right-angled triangle
08:25 sin is equal to opposite over hypotenuse. Remember as ' SOH '
09:53 cosine of angle theta = side adjacent to angle theta / hypotenuse
Remember as ' CAH ' Cosine equals Adjacent over Hypotenus.
10:28 Tangent of angle theta = side opposite to angle theta / side adjacent to angle theta.Remeber as ' TAO '. Tan is adjacent over

10:41 CBSE class 10 maths NCERT Solutions Trigonometry Exercise 8.1 Q4. Given 15 cot A = 8, find sin A and sec A.
11:10 Naming the sides
11:38 cotangent of angle theta = side adjacent to angle theta / side opposite to angle theta
12:25 Pythagoras Theorem
13:07 Trigonometric Ratio Defination
sine of angle theta = side opposite to angle theta / hypotenuse
sin is equal to opposite over hypotenuse. Remember as ' SOH '
13:26 Trigonometric Ratio Defination 'secant'
secant of angle theta = hypotenuse / side adjacent to angle theta
