Compare the formula for mutiple trapezoidal rule n=3 versus the addition of 3 single trapezoidal rule for the same problem. compare the answer, will it be the same and why?
single trapezoidal rule :
fа) + f(6) 1- (6 — а) га) 2
multiple trapezoidal rule :
f(x)) f(x,) i (b-a)o) + (2 2n
example: f(x)=0.2+25x-200x2+675x3-900x4+400x 5
a=0 b=0.8
