(a) Use the fact that 5x2 − y2 = c is a one-parameter family of solutions of the differential equation y dy/dx = 5x to find an implicit solution of the initial-value problem y dy/dx = 5x, y(4) = −10.

Then sketch the graph of the explicit solution of this problem.

Give the interval I of definition of the explicit solution. (Enter your answer using interval notation.)



(b) Are there any explicit solutions of y dy/dx = 5x  that pass through the origin? (If yes, enter the explicit solutions as a comma-separated list. If not, enter NONE.)

On page 51 we showed that a one-parameter family of solutions of the first-order differential equation dy/dx=xy^(1/2) is y=((1/4)x^4+c)^2 for c>=0. Each solution in this family is defined on (-inf,inf). The last statement is not true if we choose c to be negative. For c=-1, explain why y=((1/4)x^4+c)^2 is not a solution of the DE on the interval (-inf,inf). Find an interval of definition I on which y=((1/4)x^4+c)^2 is a solution of the DE.
