Find the equation of a curve passing throughthe origin given that the slope of the tangent to the curve at any point (xy)is equal to the sum of the coordinates of the point.



Answer -

Let F (xy)be the curve passing through the origin.

At point (xy), theslope of the curve will be

According to the given information:

This is a linear differential equation of the form:

The general solution of the given differential equation isgiven by the relation,

Substituting in equation (1), we get:

The curve passes through the origin.

Therefore, equation (2) becomes:

1 = C

C = 1

Substituting C = 1 in equation (2), we get:

Hence, the required equation of curvepassing through the origin is
