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
