I have a math problem. I have to answer these two questions, but I'm getting confused...

The first one is: Find the minor of the indicated element.
The second one is: Find the cofactor for the indicated element.

What is the difference between a minor and a cofactor? Aren't they the same thing?? So, Do I work them both out the same way??

I don't know how to do this. Can anyone help me?

The question is:
Find a point on the unit circle x^2+y^2=1 with minimum distance from the point (1,1). (Hint: Unse the parametric representation x=cost y=sint for the cirlce and find the distance as a function of t.)

I plugged in the parametic representation and got (cost)^2+(sint)^2. I don't know where to go from there.

Can someone please help me?

1- A normally pigmented man marries an albino woman.They have 3 children,1 is albino.What is the Genotype of the father?

2- 2 intensely freckled parents have 5 children,2 that are intensely freckled 3 that aren't. (Assume the trait is governed by a single pair of alleles), is the intense freckledness an example of dominant or recessive inheritance,Why?

3- A woman is heterozygous for ABO blood group with an I^A allele and an i allele.A man is heterozygous for an I^B allele and an i allele.
a- what are the possible PHENOTYPE blood types of their offspring?
b-in what % will each occur?
----------
1- I think the genotype is 1:2:1 b/c I set up a Punnett square by putting N,n on one side & A, a at the top. My results were:
NA-Na
nA-na Idk if I set it up right though.

2- I think its a result of Dominant inheritance, but I can't explain why.

3- a- I think phenotype blood types would be A or B.
b- I think it would be 50% - 50% chance

Please Help Explain these!Thanks!

Here's what I'm given. Hope I can type it clearly enough.

5
E(for sigma) f(x sub i) delta(x)
i=1

(a) f(x) = 2/3x+1

(b) delta x = 0.5

What do you do here? Many thanks!
