Cubic Splines

Function approximation using Cubic Splines and Natural Cubic Splines including discussion about figuring out if two sets of equations are splines. Important note: around 1:10 the functions also need to go through the points at the ends
ax1^3 + bx1^2 + cx1 + d = y1
ex3^3 + fx3^2 + gx3 + h = y3
