Question:
Write all trigonometric identities.
Answer:
- 1/Sin∅=Cosec∅
- 1/Cos∅=Sec∅
- 1/tan∅=cot∅
- 1/cosec∅=sin∅
- 1/sec∅=cos∅
- 1/cot∅=tan∅
- sin∅/cos∅=tan∅
- cos∅/sin∅=cot∅
- sin²∅+cos²∅=1
- cosec²∅-tan²∅=1
- sec²∅-cot²∅=1
- sin(90°-∅)=cos∅
- cos(90°-∅)=sin∅
- cosec(90°-∅)=sec∅
- sec(90°-∅)=cosec∅
- tan(90°-∅)=cot∅
- cot(90°-∅)=tan∅

★TRIGONOMETRIC RATIO★
- sin θ = Opposite Side/Hypotenuse.
- cos θ = Adjacent Side/Hypotenuse.
- tan θ = Opposite Side/Adjacent Side.
- sec θ = Hypotenuse/Adjacent Side.
- cosec θ = Hypotenuse/Opposite Side.
- cot θ = Adjacent Side/Opposite Side

=>sin²θ+ cos²θ = 1
=>1 + tan²θ = sec²θ
=>1 + cot²θ = cosec²θ
