Question

Can anyone please tell me all the trigonometric identities of class 10th ssc​

Answer 1

Answer:

In class 10th, there are basically three trigonometric identities, which we learn in trigonometry chapter. They are: Cos2 θ + Sin2 θ = 1. 1 + Tan2 θ = Sec2 θ

...

And if θ = 90,then equation (4) can be written as;

Cot290 + 1 = Cosec290.

02 + 1 = 1. ...

1 = 1.

Step-by-step explanation:

The three main functions in trigonometry are Sine, Cosine and Tangent.

...

Sine, Cosine and Tangent.

Sine Function: sin(θ) = Opposite / Hypotenuse

Cosine Function: cos(θ) = Adjacent / Hypotenuse

Tangent Function: tan(θ) = Opposite / Adjacent
