4. The error function is defined 2 erf (2) = √ √ 1²° dt. Suppose you need to compute erf (3) with an error less than 10-6 using the trapezoidal rule. How many points would you need to use to guarantee the error is within this bound? Hint: To find the bound on the derivative needed, try plotting a graph. 1 of 1 Marks: 5 4.
