6. For all value of the co-ordinates of a moving point Pare (a cos θ, b sin θ); what will be the equation to the locus of P?

a) x^{2}/a2^{2} + y^{2}/b^{2} = 0

b) x^{2}/b^{2} + y^{2}/a^{2} = 0

c) x^{2}/b^{2} + y^{2}/a^{2} = 1

d) x^{2}/a^{2} + y^{2}/b^{2} = 1

### View Answer

^{2}/a

^{2}+ y

^{2}/b

^{2}= cos

^{2}θ + sin

^{2}θ or, x

^{2}/a

^{2}+ y

^{2}/b

^{2}= 1 which is the required equation to the locus of P.

7. What curve does the locus represent if the locus of a moving point which is always equidistant from the points (2, -1) and (3, 2)?

a) Hyperbola

b) Straight line

c) Ellipse

d) Circle

### View Answer

^{2}= (x – 2)

^{2}+ (y + 1)

^{2}and PB

^{2}= (x – 3)

^{2}+ (y – 2)

^{2}

By problem, PA = PB or, PA^{2} = PB^{2}

or, (x – 2)^{2} + (y + 1)^{2} = (x – 3)^{2} + (y – 2)^{2} or, x^{2} – 4x + 4 + y^{2} + 2y + 1 = x^{2} – 6x + 9 + y^{2} – 4y + 4
or, 2x + 6y = 8 or, x + 3y = 4 ……… (1)
Clearly, equation (1) is a first degree equation in x and y; hence, the locus of P is a straight line whose equation is x + 3y = 4.

8. A point moves in such a manner that three times of its abscissa is greater by 5 than two times of its ordinate; find the equation of its locus.

a) 3y-2y=5

b) 3x-2y=5

c) 2x+3y=5

d) 2x-3y=5

12. Chords which are ___________ from the centre are equal.

a) unequal

b) equidistant

c) one third

d) two third

### View Answer

OM = ON (to prove ) OA = OC (radii of the same circle) AM = CN OR 2AM = 2 CN ( since OM ON are perpendicular to the chords and it bisects the chord and AM = MB, CN = ND )

Angle AMO and CNO = 90° ∆AOM similar to ∆CON ( R.H.S rule) OM = ON (CPCT) ( required).
