If sin θ >0 (greater than 0) and cos θ >0 (greater than 0) then the terminal point determined by θ is in what quadrant?
a. quadrant 2
b. quadrant 1
c. quadrant 3
d. quadrant 4
If sin(Θ) and cos(Θ) are both greater than zero, then (Θ) must be greater than zero and less than 90 degrees. That right there is a pretty good working definition of Quadrant-1 .
