Question

If p(x,y) is the point on the unit circle defined by real number theta, then tan theta= _____.

A. x/y

B. y/x

C. 1/x

D. 1/y

Answer 1

B. y/x

Is the correct answer. (APEX)

Answer 2

Option B is correct.

Explanation:

We have been given a point on unit circle defined by real number theta.

So, tan theta is the given by:
`tan\theta=(y)/(x)`

Equation of unit circle is
`x^2+y^2=1`

Where 1 is the radius.

Therefore, Option B is correct that is
`tan\theta=(y)/(x)`
