Algebra.Com's Answer #644973 by josmiceli(19441)![]() ![]() You can put this solution on YOUR website! Start at 0 degrees and turn the unit vector \n" ); document.write( "360 degrees at a time counter clockwise \n" ); document.write( "------------------- \n" ); document.write( "After a 360 degree turn, \n" ); document.write( " \n" ); document.write( "and the unit vector is back at 0 degrees \n" ); document.write( "------------------- \n" ); document.write( "Now turn the unit vector 270 degrees, ( going counter clockwise) \n" ); document.write( "which is 90 degrees past 180 degree location \n" ); document.write( "and 2 degrees are left, which will \n" ); document.write( "put you in the 4th quadrant \n" ); document.write( "-------------------- \n" ); document.write( "If you do any trig functions of this angle, \n" ); document.write( "the angle will be \n" ); document.write( "to the 0 degree location in the 4th quadrant \n" ); document.write( "-------------------- \n" ); document.write( "Some trig functions are negative in the 4th quadrant, \n" ); document.write( "cos( 272 ) = (+) cos( 88 ) \n" ); document.write( "sin( 272 ) = (-) sin( 88 ) \n" ); document.write( "-------------------- \n" ); document.write( "hope this helps \n" ); document.write( " \n" ); document.write( " |
