WebSep 26, 2024 · Write down the differential equations of motion (should be a 2nd order 3-element vector differential equation) Convert this to a set of six 1st order differential equations (see ode45( ) doc for example of this) Write a derivative function that takes (t,y) as input (t=time,y=6-element state vector) and outputs 6-element derivative vector) WebWe can see this represented in velocity as it is defined as a change in position with regards to the origin, over time. When the slope of a position over time graph is negative (the derivative is negative), we see that it is moving to the left (we usually define the right to be positive) in relation to the origin. Hope this helps ;) simple man cover acoustic

If you start with an equation and differentiate it, you still have an equation. That's generally and trivially true.

WebWhat if the position vector is (t, t+2), then if we take the derivative of both t and t+2, we will get velocity vector (1, 1). But it doesn't seem to be right, because we know the derivative of y=t+2 is 1 for all x values, we can write it as y=1 (x∈R), is a horizontal line rather than a single point we just calculated.
