a.) Write down the formulas for all homomorphisms from Z10 into
Z25.
b.)Write down the formulas for all homomorphisms from Z24 into
Z18.
c.)Write down the formulas for all homomorphisms from Z into
Z10.
d.)Extra: Define φ : C x → Rx by φ(a + bi) = a 2 + b 2 for all a
+ bi ∈ C x where R is the real numbers and C is the complex
numbers. Show that φ is a homomorphism.
Expand the function f(z) = (z − 1) / z^ 2 (z + 1)(z − 3) as a
Laurent series about the origin z = 0 in all annular regions whose
boundaries are the circles containing the singularities of this
function.
Describe the level surfaces of G(x,y, z) = 1 – y^2 – z. Make
sure to provide all the following: their equations, types, plots,
and a short word description of their geometric shapes.
