Question

Which are the basic trigonometric identities ​

Answer 1

Answer:

The trigonometric identities hold true only for the right-angle triangle. The six basic trigonometric ratios are sine, cosine, tangent, cosecant, secant, and cotangent. All these trigonometric ratios are defined using the sides of the right triangle, such as an adjacent side, opposite side, and hypotenuse side.

Step-by-step explanation:

Sine, Cosine and Tangent

Sine Function: sin(θ) = Opposite / Hypotenuse

Cosine Function: cos(θ) = Adjacent / Hypotenuse

Tangent Function: tan(θ) = Opposite / Adjacent

Answer 2

Answer:

The six basic trigonometric ratios are sine, cosine, tangent, cosecant, secant, and cotangent.

Consider two angles , α and β, the trigonometric sum and difference identities are as follows:

• sin(α+β)=sin(α).  
• sin(α–β)=sinα.  
• cos(α+β)=cosα.
• cos(α–β)=cosα.
