Question 1071763: Using reference angles fill in the blanks with equivilant radian values in each quadrant.
Quad 1: _____ = Quad 2: _____ = Quad 3: cos 4.1 = Quad 4: _____
I got that the Quadrant 1 value would be -cos(.958). So, would I add pi to get the rest of the values? Answer by stanbon(75887) (Show Source):
You can put this solution on YOUR website! Using reference angles fill in the blanks with equivilant radian values in each quadrant.
Quad 1: _____ = Quad 2: _____ = Quad 3: cos 4.1 = Quad 4: _____
Note: The reference angle is 4.1-pi = 0.958
Comment: The reference angle is always the acute angle between the
given angle and the nearest segment of the horizontal axis.
---
Quad 1:: -cos(0.958)
Quad 2:: cos(pi-0.958)
Quad 3:: cos(pi+0.958)
Quad 4:: -cos(2pi-0.958)
