PLS!!!! Can you just solve it with ROMBERG INTEGRATION METHOD? Everyone who solved the problem solved it with a different method.....

Problem 3: Error function is given by 2 erf(x)= = 2 e dt VTT Use Romberg Integration to O(h4) to calculate erf(1.6). Use step sizes of h=0.1 and h=0.2 (you can do the calculations in Excel). Calculate absolute error in your result by comparing with the true" value
