I need to use the theorem to determine of the equation dy/dx = y^4 - x^4 has a unique solution at point (0,7). Is that correct?

Homework Statement Given the equation dy/dx = y^4 - x^4, y(0) = 7, determine whether the existence/uniqueness theorem implies that the given initial value problem has a unique solution. Homework Equations Existence/Uniqueness Theorem The Attempt at a Solution To my understanding, you must...

3.40125 × 10^-9 is indeed the correct answer! It was my calculator that ran out of displaying digits to properly show the number. Thank you for your time.

wolfram alpha gives 3.40125... × 10^-9 , so that might be the problem. Can you verify that the way I did the question is indeed correct?

3.0E-9 is the result my calculator gives me, although the numbers may be cut-off since the calculator display is limited to 10 digits. I'll use an online calculator and see if it makes a difference

Im sorry, I don;t understand what you mean by "Post all steps", these are all the steps I have done. What more is there?

F (B->C) = G(2)(2)/(0.4^2) = 4G/0.16 F (B->A) = G(2)(2)/(0.3^2) = 4G/0.09 F (B->net) = F(B->C) + F(B->A) Can't add these together since they aren't the same direction, so use Pythagoras' theorem: F^2 (B->net) = F^2(B->C) + F^2(B->A) = sqrt((4G/0.16)^2 + (4G/0.09)^2)
