Algebra.Com's Answer #702247 by htmentor(1343) You can put this solution on YOUR website! Square both sides of each equation: \n" ); document.write( "x^2 = 4cos^2(t) -> x^2/4 = cos^2(t) \n" ); document.write( "y^2 = 9sin^2(t) -> y^2/9 = sin^2(t) \n" ); document.write( "Now add the two equations: \n" ); document.write( "sin^2(t) + cos^2(t) = x^2/4 + y^2/9 \n" ); document.write( "x^2/4 + y^2/9 = 1 \n" ); document.write( "This is the standard form for an ellipse. \n" ); document.write( " |
