Not intending to be controversial here...just curious about definitions of virginity as I overheard a debate recently which I thought was interesting...

If a virgin self inseminates, are they still a virgin?

The definition of no longer being a virgin is sexual intercouse...so as self insemination is not technically intercourse, are they still a virgin?

In this case, could a virgin birth actually be possible?

What is the definition of loss of virginity...if it is only heterosexual intercourse, are lesbians "technically" virgins?

I have never had a libido, and never been sexually attracted to either males or females.

This does not bother me, but does make relationships difficult - so at 33 I'm still single...and yes, a virgin.

However, I am interested in a platonic relationship, with the only physical side being hugs, kisses, cuddling etc - but without the sex. Would even be interested in a platonic marriage, and would consider children via self-insemination. Marrage to a gay guy who wants kids would actually be perfect situation for me.

I am aware of the existance of some platonic marriages - but normally only from the point of view of those complaining about it.

Are there any dating sites for such relationships?

I know most on this site would react the same way a lot of people do with the

"are you kidding...there is something wrong with you...get medical help...see a shrink" etc.

This is not helpful. I am not sexually active, no libido, never have had one - no medical issues and I am actually very happy with the situation, very independent and do not miss or seek sex.

Is there anyone else here who is in similar situation? How would I go about meeting a gay guy who wants kids and a platonic marriage?

I'm looking at moving to Hobart, and would like to know what it is like in Primrose Sands (Tasmania)?

Is there any public transport available in the town?

Is it a safe location?

I'm looking at moving to Hobart area, and was wondering what it is like to live in the following towns:

- Channel area - Geeveston, Cygnet, Castle Forbes Bay, Dover etc

- New Norfolk

Are these friendly towns? Safe, secure, low crime rate etc?

Basically looking for a cheap entry to the housing market somewhere that is safe and friendly, and on a regular bus route :)

Let A denote the area between the graph of f(x) = 1/x and the interval (1,2), and let B denote the area between the same graph and the interval (1/2, 1). Explain geometrically why A = B.

Please help me...I know how to do this numerically, just don't know what is meant by explain geometrically?

Please help with maths question...

let f(x) = [((a+b)*x + (a-b)|x|) / 2x ]

all values of a, b such that lim x->0 f(x) exists

I think the answer is a = b, but does this mean all values are possible? ie -inf to +inf ?

Please help me with this maths question...

Find a formula for the nth general term using powers of n, factoral expressions involving n, and/or a constant to the nth power, starting with n=1. The first four terms are (n = 1,2,3,4):

2, 2*4, 2*4*6*8*10, 2*4*6*8*10*12*14, ...

Thank you

How do I find the domain and range of the following:

1) y = ln(ln(2x))

- am I correct thinking the domain is (1 to infinity) and the range is (-inf, +inf)

2) y = -ln(-ln(2x))

- am I correct in thinking the domain = (0,1) and the range = (-inf, +inf)?

3) ln(2x)-ln(1-2x)

- am I correct in thinking the domain = (0,1) and the range = (-inf, +inf)?

I live in a very steep, hilly rural community, and am medically unable to get a drivers licence. What practical, affordable alternatives are there to driving?

I walk to and from work every day, but for further distances I need other alternatives.

Public transport is very limited here and my medical problem involves a balance and muscle coordination issue - so can't ride a bike - perhaps a tricycle, but there are a lot of very steep hills around town.

Any ideas?

Please show me how to solve the following (step-by-step) thanks.

Use Stata or Excel to find the inverse of

A=

[2 3 1]

[4 5 0]

[2 3 2]

Write out A^T, the transpose of the matrix A.

Find the inverse of A^T by partitioning

A^T = [B11 B12] Where B11 is 2x2

[B21 B22]

Confirm that in this case (A–1)^T =(A^T)–1.

Please help with the following matrix question - I dont even know where to start. Please show me a step-by-step solution.

NOTE aij and bij = a (subscript ij) and b (subscript ij).

Thank you

Prove that for an arbitrary pair of m x n (m times n) matrices A= (aij) and B=(bij), (A+B)^T = A^T + B^T.

Hint: First define C = A + B. Then apply the definition of the transform of a matrix to C and finally unpick that matrix into the separate matrices, again using the definition of the sum of two matrices. You need to write out the various steps and show how the definitions of sum and transpose apply.

Please show me step-by-step how to Invert the following matrix

A = [7 4]

[5 3]

and verify the solution by showing that AA-1 = I2.

Thank you

Please show me step-by-step how to solve the following - thanks.

(note matrix's described on multipule lines as:

[ ]

[ ]

are actually single matrix, not multipule)

a.

Determine an upper triangular matrix U (all of whose non-zero entries are positive)

such that U ^(T) U =

[4 12 8]

[12 56 32]

[8 32 20]

b.

Based on the properties of a triangular matrix, write down the determinant of U.

c.

By solving the characteristic equation, determine the eigenvalues of the matrix

A =

[4 1]

[1 4]

d.

Show that the two vectors (1,1)T and (1, -1)T are eigenvectors associated with the eigenvalues of A.

e.

By rescaling the two eigenvectors so as to be vectors of unit length, write out the spectral decomposition of A.

Please show me step by step how to use Newton’s method to find all real-valued solutions of y4 +2y = 1.

Please show me step by step how to:

a.

Find the 1st, 2nd, 3rd and 4th-order Taylor polynomials approximating the function f(x) = e–2x about x0 = ln(2). Note: the 0th-order Taylor approximation is the constant f(x) ~ f(x0).

b.

Write down the Taylor series for the function in Sigma notation.

How do I calculate the local quadratic approximation to sqrt(81.04)?

Please show me step by step - thanks

I know how to use Newtons Method to find the intercept of the x-axis, but how do you use it to find the intercept of 2 curves?

For example, use Newtons Method to find the approximate x-coordinates of all intersections for Y = e^(-x) and y = ln(x).

Newtons Method.... X(n+1) = Xn - ( f (Xn) / f '(Xn))

Please show me step-by-step - thanks

How do I find the partial differentation for:

z = (x^2y^2)/sqrt(x+y)

I need to find the dz/dx and dz/dy (partial, not full differentation)

Please show me step by step. Thank you.

Express the following in sigma notation:

1) a0 - a2 + a4 - a6 + a8

2) a1 + a2x^2 + a3x^4 + a4x^6 + a5x^8

3) 32a^5 +16a^4b + 8a^3b^2 + 4a^2b^3 + 2ab^4 + b^5

Please show me step by step how to translated these to the sigma notation (with numbers above and below sigma)

Let f(x,y,z) = z,x,y + z

Find:

a) F(x + y, x-y, x^2)

Please help - I have no idea how to solve this question, or indeed what it is asking.

Please show me step-by-step how to work it out.

Thank you
