Question

If cosec a is equal to 2 find the value of sin a and tan a

Answer 1

Answer:

sina is equal to 0.5 and tan is equal tan a is 1.

Step-by-step explanation:

Because if cosec a is 2 than first is half of it - 0.5 then we get 1-0.5 =0.5

And 2-1=1

Answer 2

Answer:

Step-by-step explanation:

cosec A = 2

1/sinA=2

Hence sinA=1/2

cos^2 A = 1-sin^2 A

=1-(1/4)

=3/4

So cosA=sqrt3 / 2

tanA=sinA/cosA

=(1/2) / (sqrt3/2)

=1/sqrt3

Another method

cosec A = 2

1/sinA=2

Hence sinA=1/2

So A=30

Hence tanA=tan30=1/sqrt3
