i am confused

4. The important error function erf(z) is defined by the integral erf ( z) = e dt. Derive the Maclaurin series 2 (-1)jz2j+1 erf (z) = j!(2j + 1) ' Z EC. 1=0 Hint: Use the known Maclaurin series for er to write down the series for e-t. Then do term-by-term integration, explaining why it is allowed
