# How do you use the unit circle to find values of #cscx#, #secx# and #cotx#?

##### 1 Answer

Start from the definitions:

Based on this, all we need to define using the unit circle are

By definition, *ordinate* (Y-coordinate) and *abscissa* (X-coordinate) of a point lying on a unit circle at the end of a radius that forms an angle *radians* with the positive direction of the X-axis (counterclockwise from X-axis to this radius).

Using all the above, let's, for example, find

Angle *abscissa* of point

Therefore,

From this we find
