Yes, putting Euler's Formula on that graph produces a circle: e ix produces a circle of radius 1 . And when we include a radius of r we can turn any point (such as 3 + 4i) into re ix form by finding the correct value of x and r: Example: the number 3 + 4i. To turn 3 + 4i into re ix form we do a Cartesian to Polar conversion: r = √(3 2 + 4 2) = √(9+16) = √25 = 5; x = tan-1 ( 4 …Euler angles are a method of determining the rotation of a body in a given coordinate frame. They can be defined as three rotations relative to the three major axes. Euler angles are most commonly represented as phi for x-axis rotation, theta for y-axis rotation and psi for z-axis rotation. Any orientation can be described by using a ... I do not think there is a built in Matlab function to perform what you want.

Thanks for the tip! Unfortunately, I know about ode23 and that is not Euler's method. Sometimes ode solvers like ode23 and ode45 make hidden assumptions when calculating that you don't know about so I need to use Euler's method to clearly see the iterative loop and how the ode is being solved.
