angle *θ* in standard
position contains the point (7,24). What is
sin(*θ*)

**Problem : **
Which trigonometric functions are independent of the distance between a
point and the origin (when the terminal side of
an angle in standard position contains that point)?

**Problem : **
If the sine of an angle is negative, which other trigonometric functions
will definitely have negative values?

**Problem : **
In which two quadrants is the cosine function
always positive?

**Problem : **
