Q4)

The error function, erf(x), is defined by the following Write an expression for the function, f(x), if it is known that f'(x) = cos(x2) and 4) = 7. Give your answer using the form below. Hint: See example 5 on page 322 of the textbook. Write an expression for the function, F(x), if it is known that F(x) = e -2 and F(0) = 3 . Give your answer using the form below. Hint: See example 5 on page 322 of the textbook. Does F(x) have a maximum value for 0

Explanation / Answer

Q1)

a) 0

b) 6x^2 e^(-x^6) / sqrt(pi)

-------------

Q2)

C = 7

a = 4

A(t) = cos(t^2)

-------------------

Q3)

a)

C = 3

a = 0

A(t) = e^(-t^2)

b)

3.882

---------------

Q4)

Yes

sqrt( pi )

0.895
