**Problem : **
The terminal side of
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)?

Tangent and cotangent

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

Cosecant. The others can have either positive or negative values when sine
is negative.

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

Quadrants I and IV
