Question

Which of the following is equal to tan O using coordinates on the unit circle?

Answer 1

The expression which is equal to tan O using coordinates on the unit circle is y/x. Option A is correct.

What is right angle triangle property?

In a right angle triangle, the ratio of the opposite side to the base side is equal to the tangent angle between them.

$\tan\theta=\dfrac{b}{a}$

Here, (a) is the base side, (b) is the opposite side.

Let suppose y is the length of opposite side in a unit circle and x is the length of base side. Thus, the value of tan theta is:

$\tan\theta=\dfrac{y}{x}$

Hence, the expression which is equal to tan O using coordinates on the unit circle is y/x. Option A is correct.
