Exercises

Follow the instructions for the exercises below

1. Find the decimal value of the error function at 4.5, 5 and 100

   evalf(erf(4.5))
evalf(erf(5))
evalf(erf(100))

2. Plot the error function from -10 to 10

   plot(erf(x), x=-10..10)

3. Take the integral of $e^{-t^2}$ (Name the expression ex3)

   ex3:= exp(-t^2)
int(ex3, t)

4. Take the derivative of the gamma function

   expr:= GAMMA(x)
diff(expr, x)
