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:

3x 3 + y 2 – 1 = 0

x4 – 10y2 + 2 = 0

The last commands in the tutorials have a wrong solution

The book has:

ans =
5       1       1       0       0       1

ans  =
1       1       1       0       0       1
