00:02 CBSE class 10 maths NCERT Solutions TrigonometryQ7. If cot theta = 7/8 evaluate : 00:30 (i) 04:57 (ii)
00:45 Consider the trigonometric expression
03:08 consider Trigonometric Ratio
sine of angle theta = side opposite to angle theta / hypotenuse
sin is equal to opposite over hypotenuse.
Remember as ' SOH '
03:52 CBSE class 10 maths NCERT Solutions Trigonometry Q8. If 3 cot A = 4, check whether (1-tan²A)/(1+tan²A) = cos²A - sin²A or not.
06:04 Take LHS of trigonometric equation
06:30 Reciprocal Identity.
The ratios cosec A, sec A and cot A are respectively, the reciprocals of the ratios sin A, cos A and tan A
07:52 Take RHS of trigonometric equation
08:11 Apply Trigonometric Ratio
tangent of angle theta = side opposite to angle theta / side adjacent to angle theta.
08:45 Pythagoras Theorem
In a right triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.
09:16 cosine of angle theta = side adjacent to angle theta / hypotenuse
Remember as ' CAH ' Cosine equals Adjacent over Hypotenus.
09:45 solve trigonometric equation
11:10 CBSE class 10 maths NCERT Solutions Trigonometry Q9. In triangle ABC, right-angled at B, if tan A = 1/ sqrt (3) : find the value of:
(i) sin A cos C + cos A sin C (ii) cos A cos C – sin A sin C
11:30 Naming the sides | Determining the sides of right angles triangles using Trigonometric Ratio Tan.
12:21 tangent of angle theta = side opposite to angle theta / side adjacent to angle theta.
Remeber as ' TAH '. Tan is adjacent over Opposite
13:23 Pythagoras LAW
15:35 (i)
16:48 (ii)

In this tutorial we show you how to name the sides of a right-angled triangle in preparation for using trigonometry to find lengths and angles in right-angled triangles

In this tutorial I show you how to find the length of a side by using trigonometry when the missing side is in the top of the trigonometry ratio fraction.
this is done if you are given the opposite angle and the two other sides.
The word ‘trigonometry’ is derived from the Greek words ‘tri’ (meaning three), ‘gon’ (meaning sides) and ‘metron’ (meaning measure). In fact, trigonometry is the study of relationships between the sides and angles of a triangle.
We will study some ratios of the sides of a right triangle with respect to its acute angles, called trigonometric ratios of the angle. Learn how to solve the problems based on the relation between the trigonometrical ratios.
