  4. FOR 100% SUCCESS IN JEE MAIN AND ADVANCED (11T-JEE) Formation of Differential Equation: The differential equation corresponding to a family of curve can be obtained by using the following steps: Identify the number of essential arbitrary constants in equation of curve. NOTE: If arbitrary constants appear in addition, subtraction, multiplication or division, then we can club them to reduce into one new arbitrary constant. (b) (c) Differentiate the equation of curve till the required order. Eliminate the arbitrary constant from the equation of curve and additional equation obtained in step (b) above.

  5. FOR 100% SUCCESS IN JEE MAIN AND ADVANCED (11T-JEE) Example Form a differential equation of family of straight lines passing through origin Sol. Family of straight lines passing through origin is y = mx where'm'is parameter. Differentiating w.r.t. x dym dx Eliminating 'm' from both equations dy y dx X which is the required differential equation. MATHEMATICS FOR IIT-JEE ER. VINEET LOOMBA (IIT RooRKEE)


  6. FOR 100% SUCCESS IN JEE MAIN AND ADVANCED (IIT-JEE) Example: Form a differential equation of family of circles touching x-axis at the origin? Sol. Equation of family of circles touching x-axis at the origin is where is parameter Eliminating from (i) and (ii) 2xy dy dx X which is required differential equation MATHEMATICS FOR IIT-JEE ER.

  7. FOR 100% SUCCESS IN JEE MAIN AND ADVANCED (IIT-JEE) Example: By the elimination of the parameters h and k, find the differential equation of whiclh (x - h)+ (y - k)2- a2, is a solution Solution: Three relations are necessary to eliminate two constants. Thus, besides the given relation, we require two more and they will be obtained by differentiating the given relation twice successively Thus we have)(-) x 0 From (i) and(ii), we obtain dxdx 2 dx and x -h- substituting these values in the given relation, we obtain Which is the required differential equation MATHEMATICS FOR IIT-JEE ER.
