A simulation that models simple harmonic motion in 2 dimensions

Here, you can control:

• the maximum path points that your shm trajectory can have
• the linear interpolation factor - higher values are less smooth than lower values, but they follow the path of the shm more accurately while being less susceptible to framerate changes
• the radius of the circle and the line size of the path
• the time step - higher values make the simulation run faster, but you don't see every frame, only what's calculated <timestep> frames from the last shown frame
• the frequency - you can change the X and Y frequencies to achieve different effects
• the box sizes - you can change the X and Y box sizes to change the aspect ratio and size of the resulting animation
• the phase difference - this is the phase applied to the sin function such that it leads the cos function by <phase°>
• the phase speed - this is the amount in degrees that the phase is increased by each frame
• the visibility of the circle and the path

Note that the simulation may seem like it vibrates at high time-steps and relatively stable x and y frequencies. This happens due to lack of smoothing of the path lines drawn by the circle. A lower frequency combination will have a more smooth path than a higher frequency combination: Ex. 2:3 will have a more smooth path than 32:48
