A little talk on Sine, Cosine and Tangent || in Hindi for Class 9

In this Mathematics video in Hindi for Class 9 we talked about Sine, Cosine and Tangent. In short these are named as sin, cos and tan.
These apply to a right triangle.
sin θ = opposite/hypotenuse
cos θ = adjacent/hypotenuse
tan θ = opposite/adjacent
In this video we talked about the fundamentals of these trigonometric functions and we also discussed on how to use these functions.

    Good work, it would be better if you should have talked about on the Ration and relationship as trigonometry is all about ratio and relationship between the triangle's sides. and more is that how an angle can be equal to a value, it means angle is nothing but a value derived from the relation of the sides. I would write a relationship like that Cos theta= adjacent:hypotenuse.

  • @edupoint.secondary

    Good thinking. It would be better if you revisit the concept of ratio. Ratio can be representes as x:y or x/y. Both are the same. And angle is not derived from anything. It is an independent quantity. That is why it is included in the extended base quantities. It is an entirely different story that you can interrelate angles and the lengths of the sides of a right triangle. Learn, learn, learn.... Grow your concept.....

    Make theta = 85° Then 86° Then 87° and so on upto 90°. You will get the feeling. For 90° the opposite side will be equal to the hypotenuse. Hence, sin 90° = 1 For 90° adjacent vanishes. Hence, cos 90° = 0.
