Consider the ellipse whose equation is (x-3)^2/ 25 + (y-4)^2/16 =1 \n" ); document.write( "a. what is the center?...... (3,4) \n" ); document.write( "b. What are the lengths of the major and minor axes, \n" ); document.write( "Major: Vertices are (3-5,4) and (3+5,4) or (-2,4) and (8,4) \n" ); document.write( "So the length of the major axis is 8--2 = 10 units. \n" ); document.write( "-------------- \n" ); document.write( "Minor: Co-vertices are (3,4-4) and (3,4+4) or (3,0) and (3,8) \n" ); document.write( "So the length of the minor axis is 8-0 = 8 units \n" ); document.write( "----------- \n" ); document.write( " and the distance between the foci? \n" ); document.write( "a=5, b=4, so c=sqrt(25-16) = 3 \n" ); document.write( "So distance between the foci is 2*3 = 6 \n" ); document.write( "------------------------------------- \n" ); document.write( "c. find the coordinates of the focal points. \n" ); document.write( "(3-3,4) and (3+3,4) or (0,4) and (6,4) \n" ); document.write( "====================== \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( " \n" ); document.write( " |
