Given the functions
x[n] = 1.3n + Sin[n]
y[n] = 2(1 + Cos[n/2])
Assuming that these two functions are used to create a parametric plot where x = x[n] and y=y[n]
Ah.. but lets say that x[n] is..
x[Pi/2] = (1.3(Pi))/2 + 1 = 3.0420352248333655
How would you combine these two functions to find the derivative of y= f[x]?
so you could work out the slope at that particular point?

Why I am seeing this post as yellow colored? Or anybody else seeing the same?

changed it a bit..had it wrong at first. I dont think finding an f[x] is very doable

its a paid question to the qualified helpers.. they go yellow
