1. (a)  Determine the following integral. One may need to use a numerical approxima-tion.

∫π/40exp(x3) sin(x4)dx

(b)  Using Maple, compute the 5th order Taylor series around x= 0fortanh(sin(x))and plot the accompanying polynomial.

(c)  Using Maple, calculate the following sum


What is the sum for= 3,N= 20andM= 43?


(d) (15 marks) Using Maple, calculate and simplify if possible the inverse of the transpose of E, where Eis given by E=[a−√3ba]For what values of a does the inverse exist?


2. (30 marks) Consider the following polynomial

f(x) = 3×4−4×3−2×2+x+15

UsingMaple, define the function f(x), plot the polynomial for x∈[−1,2], determine its (real)zeros (numerically), and determine its derivative. Also plot in the same graph for f(x)the points(x, f(x))for which the function obtains local minima and maxima, as large red dots.



3.  The Fibonacci numbers can be defined as:



withF0= 0andF1= 1. Alternatively, an explicit expression is Fn=an−(−a)−n√5


witha=1+√52. Plot the points(xn, yn) = (n, Fn)for the first 100 Fibonacci numbers.If you don’t submit the Maple document file with extension.mwfile grading can not be carr
