An ellipse having foci at (3, 3) and (–4, 4) and passing through the origin has eccentricity equal to

Test: Ellipse- 2 - Question 6
Save

A tangent having slope of - 4/3 to the ellipse +  = 1 intersects the major & minor axes in points A & B respectively. If C is the centre of the ellipse then the area of the triangle ABC is

Detailed Solution: Question 6

Since the major axis is along the y-axis.
∴ Equation of tangent is x = my + [b2m2 + a]1/2
Slope of tangent = 1/m = −4/3    
⇒ m = −3/4
Hence, equation of tangent is 4x+3y=24 or  
x/6 + y/8 = 1
Its intercepts on the axes are 6 and 8.
Area (ΔAOB) = 1/2×6×8
= 24 sq. unit

Test: Ellipse- 2 - Question 7
Save

The equation to the locus of the middle point of the portion of the tangent to the ellipse  +  = 1 included between the co-ordinate axes is the curve

Test: Ellipse- 2 - Question 8
Save

An ellipse is drawn with major and minor axes of lengths 10 and 8 respectively. Using one focus as centre, a circle is drawn that is tangent to the ellipse, with no part of the circle being outside the ellipse. The radius of the circle is

Detailed Solution: Question 8

2a=10,a=5
2b=8,b=4
b2=a2(1−e2)
e2=1−16/25
e=3/5
Focus of ellipse (±3,0)
Taking (3,0) as centre, circle is drawn,
Radius of circle will be =5−3 = 2 units.

Test: Ellipse- 2 - Question 9
Save

Which of the following is the common tangent to the ellipses  +  = 1 & + = 1 ?

Detailed Solution: Question 9

For x2/(a2 + b2) + y2/b2 = 1
Equation for tangent y = mx +- [(a2 + b2)m2 + b2]1/2
For x2/a2 + y2/(a2 + b2) = 1
Equation for tangent y = mx +- [a2m2 + (a2 + b2)}1/2
For common tangent: [(a2 + b2)m2 + b2]1/2 = [a2m2 + (a2 + b2)}1/2
(a2 + b2)m2 + b2 = a2m2 + (a2 + b2)
a2m2 + b2m2 + b2 = a2m2 + (a2 + b2)
b2m2 = a2
m = +- a/b
Equation for tangent : y = +- ax/b +-[(a2 + b2)a2/b2 + b2]1/2
y = +- ax/b +-{[a4 + a2b2 + b4]1/2}/b
by = +- ax +-{[a4 + a2b2 + b4]1/2}

Test: Ellipse- 2 - Question 17
Save

PQ is a double ordinate of the ellipse x2+ 9y2 = 9, the normal at P meets the diameter through Q at R, then the locus of the mid point of PR is

Detailed Solution: Question 17

Equation of ellipse : x2/9 + y2/1= 1
Co−ordinates of point P is : (acosθ , bsinθ)
Equation of normal at point (x1, y1) is :
a2x/x1 − b2y/y1 = (ae)2
Equation of normal at point P is:
ax/cosθ− by/sinθ= (ae)2−−−−−(1)
Equation of diameter at Q is : y = (−b/a)tanθ−−−−−(2)
Point of intersection of equation 1 and 2 is :
ax/cosθ + (b2/acosθ) = (ae)2
Or , x = ae2cosθ − b2/a2
And y = − be2sinθ + b3/a3 (from 2)
∴ Point R(ae2cosθ − b2/a2 , − be2sinθ + b3/a3)
Let mid point of PR is (h,k)
h =[acosθ + ae2cosθ − (b2/a2)]/2
Or , 2h + b2/a2= acosθ + ae2cosθ
Or , cosθ= [2h + (b2/a2)/(a + ae2)]
k = [bsinθ − be2sinθ + (b3/a3/2)]/2
Or , sinθ = [2k − (b3/a3)/(b − be2)]
On squaring adding we get :
[2h + (b2/a2)]/(a + ae2)2 + [2k − (b3/a3)] / (b − be2)2= 1
Which is an equation of ellipse.

Test: Ellipse- 2 - Question 18

Detailed Solution: Question 19

Given,  x2/5 + y2/3= 1
We know S1F1 × S2F2 = b2
∴ S1F1 × S2F2 = 3
