If O is an angle in standard position and its terminal side passes through the point(-15,-8), find the exact value of tan 0 in simplest radical form.



Answer :

The definition of the tangent function for a angle in standard form is given by:

[tex]\tan \theta=\frac{y}{x}[/tex]

where x and y are the coordinates of the terminal point (x,y).

Then in this case we have:

[tex]\tan \theta=\frac{8}{15}[/tex]
