Point Q(-12,-9) is on the terminal arm of a circle in standard position\r
\n" ); document.write( "\n" ); document.write( "a) Give exact coordinates of a point P(x,y) on the terminal arm of a unit circle
\n" ); document.write( "b) What is the value of tan(t) and the measure of angle t?
\n" ); document.write( "----
\n" ); document.write( "tan(t) = y/x = 3/4
\n" ); document.write( "--> t =~ 36.87 + 180 = 216.87 degs
\n" ); document.write( "====================================
\n" ); document.write( "a) Give exact coordinates of a point P(x,y) on the terminal arm of a unit circle
\n" ); document.write( "r = sqrt(s^2 + y^2) = 15
\n" ); document.write( "----
\n" ); document.write( "On a unit circle, x = -12/15 = -4/5
\n" ); document.write( "y = -9/15 = -3/5
\n" ); document.write( "--> (-4/5,-3/5)
\n" ); document.write( "
\n" );
