Question

If sino = x and seco = y, then tano is
(a) xy
(b) x/y
(c) y/x
(d) 1/xy​

Answer 1

Answer:

The correct answer is (a).

Step-by-step explanation:

Given,

sin θ = x

And,

sec θ = y

1/cos θ = y

cos θ = 1/y

Now,

tan θ = sinθ / cosθ

= x/ 1/y

= xy

So, the correct answer is (a)

Answer 2

Given :  sin∅ = x  and  sec∅ = y

To Find : tan∅

(a) xy

(b) x/y

(c) y/x

(d) 1/xy​

Solution:

tan∅ = sin∅ / cos∅

=> tan∅ = sin∅ ( 1/ cos∅)

sec∅ = 1/cos ∅

tan∅ = sin∅  . sec∅

Substitute sin∅ = x

and sec∅ = y

=>  tan∅ =  xy

Correct option is a) xy
