Is trigonometry useful in life?

Trigonometry and its functions have an enormous number of uses in our daily life. For instance, it is used in geography to measure the distance between landmarks, in astronomy to measure the distance of nearby stars and also in the satellite navigation system.

What are the 11 trigonometric identities?

Sum and Difference of Angles Trigonometric Identities

• sin(α+β)=sin(α). cos(β)+cos(α). sin(β)
• sin(α–β)=sinα. cosβ–cosα. sinβ
• cos(α+β)=cosα. cosβ–sinα. sinβ
• cos(α–β)=cosα. cosβ+sinα. sinβ
• tan(α+β)=tanα+tanβ1–tanα. tanβ ⁡ ( α + β ) = tan ⁡ ⁡ β 1 – tan ⁡ α .
• tan(α–β)=tanα–tanβ1+tanα. tanβ ⁡ ( α – β ) = tan ⁡ ⁡ β 1 + tan ⁡

What are the 10 trigonometric identities?

1 – Sin2 A = Sin2 A + Cos2 A – Sin2 A = Cos2 A.

Prove that Sec2P – tan2P – Cosec2P + Cot2P = 0.

Sec2P – tan2P – Cosec2P + Cot2P = 1 + tan2P – tan2P – (1 + Cot2P) + Cot2P.

= 1 + 0 – 1 – Cot2P + Cot2P.

= 0.
