JEE Main 2022 Mathematics question
Let and be two distinct solution of the differential equation dy/dx = x + y, with and respectively. Then, the number of points of intersection of and is
Answer: (1)
Solution
Put x + y = t: dt/dx − 1 = t, so dt/(t + 1) = dx and |t + 1| = , i.e. |x + y + 1| = . For : C = 1, and for : C = 2. So
