In a circle of radius r, an arc of length kr will subtend in angle of __________ radians at the center: |
|
3 |
|
|
4 |
To convert any angle in radians into degrees, we multiply the measure by: |
|
5 |
(1 - sin<sup>2</sup>Θ) (1 + tan<sup>2</sup>Θ) = |
|
6 |
The quadrant of an angle Θ is determined by its: |
- A. sign
- B. value
- C. ratio
- D. magnitude
|
7 |
If sin α < 0 and cos α > 0, then α lies in: |
|
8 |
If sin Θ + cosec Θ = 2, then sin<sup>2</sup> Θ + cosec<sup>2</sup> Θ = |
|
9 |
