Unformatted text preview: te counter-clockwise from the positive x-axis. One full π revolution accounts for 2π = 84 of the radian measure with π or 1 of a revolution remaining. 4 8 π π We have γ as a Quadrant I angle. All angles coterminal with γ are of the form θ = 94 + 84 · k , π 7π 17π where k is an integer. Working through the arithmetic, we ﬁnd: 4 , − 4 and 4 . π π 4. To graph φ = − 52 , we begin our rotation clockwise from the positive x-axis. As 2π = 42 , π 1 after one full revolution clockwise, we have 2 or 4 of a revolution remaining. Since the terminal side of φ lies on the negative y -axis, φ is a quadrantal angle. To ﬁnd coterminal π π π π angles, we compute θ = − 52 + 42 · k for a few integers k and obtain − π , 32 and 72 . 2 10.1 Angles and their Measure 603 y y 4 4 3 3 2 2 1 1 −4 −3 −2 −1 −1 −2 −3 1 2 3 x 4 γ= −4 −3 −2 −1 −1 9π 4 in standard position. 1 2 3 4 x −2 9π 4 −3 −4 γ= π φ = − 52 −4 π φ = − 52 in standard position.
