      @You12783 6 років тому +5

      well another solution is that when you draw the curve for sinx and sqrt(sinx) ... you'll see that from 0 to pi/2 they're almost identical ... thus they cover an area of say 1 square units ... which is definitely less than 1.25 which is approximately sqrt(pi/2)

    I've found a differential equation that will take you longer than a minute to solve ... this one has been causing me headaches ever since I alighted upon it ...
    y(dy/dx) + y = f(x), where f(x) is an integrable function.
    This one refuses to yield to any substitution I try. Does there exist a closed form for y satisfying this equation, for any integrable f(x)?

    So isn't it necessary that a=1?
