The result for the command exp(pi*sqrt(163)) is displayed as 2.6354e+17 while the exact display by Matlab is 2.6354e+017. Similarly 1.6331e+016

After defining variables 'x' and 'y' as real, the definition of 'inner_product' must be given again to obtain the 'inner_product' as 'x^2 +y^2'

The book has:

v=[x;y];

inner_product= v‘*v

syms

x y real

inner_product

To be changed to:

v=[x;y];

inner_product=v‘*v

syms x y real

inner_product=v‘*v

Problem 1(b): The book has: Show that (*x^2 -4x + 4*) is a factor of *"f"*. The factor of the expression is (*x^2 - 4x - 4*)

Problem 1(c): There is no function called ‘factorize’ as mentioned in the question rather the function looked for is ‘factor’

Problem 4: The heading of the question is ‘**Solving simultaneous nonlinear equations’. **The nonlinear equations are:

x^{4} – 10y^{2} + 2 = 0

The last commands in the tutorials have a wrong solution

The book has:

ans =

5 1 1 0 0 1

Instead of:

ans =

1 1 1 0 0 1
