## Re: Elementary Differential Equations

How can I view the topic nonhomogeneous differential equation and its applications?

## Re: Elementary Differential Equations

Where is the topic Variable Separable?

## Re: Elementary Differential Equations

I found this: http://www.mathalino.com/tag/reviewer/variables-separable

## Re: Elementary Differential Equations

It is here: http://www.mathalino.com/node/489

## Re: Elementary Differential Equations

its also separation of variables.. just the same

## Re: Elementary Differential Equations

Where can I see the lecture about the Families of Curves? tnx :')

## Re: Elementary Differential Equations

where is the topic Families of Curves?

## Re: Elementary Differential Equations

please give me more examples of differential equations, elimination of arbitary constant

## Re: Elementary Differential Equations

can you eliminate the constant in:

1.) y= asin3x + bcos5x

2. y= aue^3x + bve^(-4x) [a&b are constants]

3. ax^2 +bxy +cy^2 = 0

## Re: Elementary Differential Equations

Yes you can. Derive the equation 1 3 times then equate the coefficients.

## Re: Elementary Differential Equations

Example of Wronksian

## Re: Elementary Differential Equations

Wheres the topic for family of curves and particular differential equations?

## Re: Elementary Differential Equations

i need help . .i need the differential equation of all circles tangent to x-axis and radius can be anywhere in 1st -4th quadrant

## Re: Elementary Differential Equations

Are there any other samples for Elementary Applications besides Newton's Law of Cooling and Simple Chemical Conversion? Thanks in advance ☺️
