    First order diffrential equations.

    guys im realllly bad at these i need to get them in for extra credit to boost my gpa gimmi a hand?

    Solve

    a)dx/dt = -t power 4

    b)dy/dt = 4 / y power 2 + 3

    c)dy/dx = -8 y power 3

    d) xy dy/dx = x + 4x power 2 / 5y

    2)solve with subsittution y=vx

    dy/dx= 6xy/x power 2 - y power 2

    I assume that if they're for extra credit then your professor will be expecting what you hand in to be your work and not the work of other people (we don't need the extra credit). Even if you do have a gimmi hand.

    I could; with an extra line of credit I could get a new 120" 3D/HD tv and a larger house to put it in
