Hello community, im still a bit shaky on the concept so i have to find the equations and plot the natural cubic spline that interpolates the data points (0,3), (1,5), (2,4), (3,1) but im not really sure where to start? i know i have to use the cubic spline function but im not sure where to go from there. Thank you

So would i use the pp(csape) function? how would that get me to the equation i need though?

Please stop posting the same question multiple times. I already showed you how to solve the problem in your other question, in fact, there using csape.
