Mathematics · Differential Equations
If y = -1 when x = 0, then the particular solution of the differential equation (1 + e2x) dy + (1 + y2) ex dx = 0 is:
- 1tan-1(y) + tan-1(ex) = 0✓
- 2tan-1(xy) + tan-1(ex) = 0
- 3tan-1(y) + tan-1(x ex) = 0
- 4None of the above
Correct answer
tan-1(y) + tan-1(ex) = 0
