If tan(tita) = 2 then find the values of other trigonometric ratios.

Nady [450]

<h2>Answer:</h2>

<u>We know that</u>,

sec²θ = 1 + tan²θ

⇒ sec²θ = 1 + (2)²

⇒ sec²θ = 5

⇒ secθ = √5 …[1]

<u>Also</u>,

⇒ cosθ = 1/secθ

⇒ cosθ = 1/√5 …[2]

<u>Now, using</u>

tanθ = sinθ/cosθ

⇒2 = sinθ/1/√5

⇒2 = sinθ√5

⇒sinθ = 2/√5 …[3]

<u>Also</u>,

cosecθ = 1/sinθ

⇒cosecθ = √5/2 …[4]

cotθ = 1/tanθ

⇒cotθ = 1/2 ….[5]
