previously miley and mandy talked and mandy told the teachers to call her hannah montana
now in home room
mandy:the answer is
If you
think of the area in the first quadrant with x and y both positive,
the area is given by INT(0 to a)[y dx]
Let the equation of the ellipse in parametric form be: x= a cos(theta) y= b sin(theta)
dx = -a sin(theta) d(theta)
Area = INT(pi/2 to 0)[-b sin(theta) * a sin(theta) * d(theta)] = INT(0 to pi/2)[absin^2(theta) * d(theta)] = INT(0 to pi/2)[(ab/2)(1-cos(2theta) * d(theta)] = (ab/2)[(theta) - (1/2)sin(2theta)] from 0 to pi/2 = (ab/2)[pi/2 - 0] = pi*ab/4
The total area of the ellipse will be 4 times this area, so:
Area of ellipse = pi*ab
hrt:correct ms.montana
yes joe
joe:where is mandy lovato
miley:she moved to la she got a free scholorship for a high school there
mandy:oh i heard about that she told me her bestfriend since our mamas were pegnaunt
