Problems
Problem 1.1:
The terminal side of
angle
θ in standard
position contains the point (7,24). What is
sin(θ)
[Solution]
Problem 1.2:
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)?
[Solution]
Problem 1.3:

will definitely have negative values?
