WebFrom the 2nd derivative finite difference formula, we know that y − 1 − 2 y 0 + y 1 h 2 = − g, therefore, we can solve for y − 1 and then get the launching velocity. See the calculation below. y_n1 = -9.8*h**2 + 2*y[0] - y[1] (y[1] - y_n1) / (2*h) 34.5 We can see that we get the correct launching velocity using the finite difference method.

WebSo if this is 0, c1 times 0 is going to be equal to 0. So this expression up here is also equal to 0. Or another way to view it is that if g is a solution to this second order linear homogeneous differential equation, then some constant times g is also a solution. So this is also a solution to the differential equation. WebConsider the second order linear difference equation axk + 2 + bxk + 1 + cxk = 0, where a, b, and c are constants. To solve this equation, select a suitable trial solution of the form xk = Aλk, where λ is a yet to be determined constant. Thus, xk + 1 = Aλk + 1 = Aλλk, and xk + 2 = Aλk + 2 = Aλ2λk.
