Goldstein/SCHNIEDER/LAY, CALCULUS AND ITS APPLICATIONS , 11e – Slide #9 Determining an Angle EXAMPLE EXAMPLE SOLUTION SOLUTION Give the radian measure of the angle described. The angle above consists of one full revolution (2π radians) plus one half- revolutions (π radians). Also, the angle is clockwise and therefore negative. That is, ( 29 . 3 2 π - = + - = t
