What is the rule for the composite transformation formed by a translation 2 units to the left and 3 units up, followed by a 90 degree rotation counterclockwise? \n" ); document.write( "======== \n" ); document.write( "2 to the left: x goes to x+2 \n" ); document.write( "3 up: y goes to y+3 \n" ); document.write( "90 degree rotation counterclockwise: (x,y) goes to (-y,x) \n" ); document.write( "------ \n" ); document.write( "Rule: \n" ); document.write( "If you start with y = x \n" ); document.write( "2 to the left gives y= x+2 \n" ); document.write( "--- \n" ); document.write( "then 3 up gives y = x+2+3 \n" ); document.write( "or y = x+5 \n" ); document.write( "--- \n" ); document.write( "then the rotation gives: \n" ); document.write( "x = -y+5 \n" ); document.write( "--- \n" ); document.write( "Final result is y = -x+5 \n" ); document.write( "=============================== \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( "============== \n" ); document.write( " |
