Answer 2

Answer:

Sinθ = 1 / √2 and Cosθ = 1 / √2

Step-by-step explanation:

Given---> tanθ = 1

To find---> Value of Sinθ and Cosθ .

Solution----> ATQ,

tanθ = 1

=> tanθ = tan 45°

=> θ = 45°

Now , we have to find value of Sinθ ,

Sinθ = Sin 45°

=> Sinθ = 1 / √2

Now , we find value of Cosθ ,

Cosθ = Cos45°

=> Cosθ = 1 / √2

Additional information--->

1) Sin²θ + Cos²θ = 1

2) 1 + tan²θ = Sec²θ

3) 1 + Cot²θ = Cosec²θ
