Question

If the terminal point of ø is (1,0), what is tan ø?

Answer 1

Given:

The terminal point of $\phi$ is (1,0).

To find:

The value of $\tan\phi$.

Solution:

If the terminal point of $\theta$ is (x,y), then

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

It is given that the terminal point of $\phi$ is (1,0).

Here, x-coordinate is 1 and the y-coordinate is 0. Using the above formula, we get

$\tan \phi=\dfrac{0}{1}$

$\tan \phi=0$

Therefore, the value of $\tan \phi$ is 0.
