Question

Use Euler's method with step size 0.5 to compute the approximate y-values y1, y2, y3 and y4 of the solution of the initial-value problem y' = y − 3x, y(4) = 0.

Answer 1

the function g(x)=x^2+5x, x>=p is one to one. find the least value of p, the range of g, sketch the graph of this function.

Answer 2

g(x) = (x + 5/2)^2 - 25/4
p = -25/4

there are Euler's method calculators online.

Answer 3

i had figured it out before actually, and had posted saying that, so not sure why my comment about figuring it out isn't there.
