(a) Verify that y = tan(x + c) is a one-parameter family of solutions of the differential equation y' = 1 + y². O Differentiating y = tan(x + c) we get y'=csc(x + c) or y' = 1 + y². Differentiating y=tan(x + c) we get y'= 1 + tan²(x + c) or y'= 1 + y². O Differentiating y = tan(x + c) we get y'= 1 + sec²(x + c) or y'= 1 + y². O Differentiating y = tan(x + c) we get y'= tan²(x + c) or y'= 1 + y². O Differentiating y = tan(x + c) we get y' = sec(x + c) or y'= 1 + y². (b) Since f(x, y) = 1 + y² and affay = 2y are continuous everywhere, the region R in Theorem 1.2.1 can be taken to be the entire xy-plane. Use the family of solutions in part (a) to find an explicit solution of the first-order initial-value problem y' = 1 + y², y(0) = 0. y=tan(x) Even though x = 0 is in the interval (-2, 2), explain why the solution is not defined on this interval. Since tan(x) is discontinuous at x = 2 the solution is not defined on (-2, 2). (c) Determine the largest interval I of definition for the solution of the initial-value problem in part (b).
