Formation of differential equations.
Q. 1. Form the differential equation of the following family of curves:
- y=
- y = asin(x+b)
- y = Acosmx + Bsinmx ,
- y = c+cx+cx2
- y = e2X (a+bx)
- ex (acosx +bsinx)
- Y = ae3X + be-2x
- (x-a)2 + (y-b)2 = r2 .
- Family of ellipses having foci on x-axis and centre at the origin.
Q. 2. Family of circles touching x-axis at the origin.
Q.3. Family of parabolas having vertex at the origin and axis along positive direction of x-axis.
Q.4 Family of curves y = ae2x + be-x
Q.5. Family of circles having centre on the x- axis and the radius is unity.
Q.6. Family of circles in the first quadrant which touches the co-ordinate axis.
