Thank you

Hello, I've a book in cell biology (it's an advanced book not a crash course or something) where's written that peripheral proteins are loosely connected to the membrane. However in most sources on the internet it's written that the protein is temporally adhered to the membrane. I'm a bit...

Hello, I've some two distributions, how can I find the distance between those two distributions? is the difference between the mean values would be the distance ?

no, I'm not sure... but what am I doing wrong ?

I don't understand what am I doing wrong!? please help: I need to find the inverse of A, so and but Matlab returns me

thank you

I tried multiplying (I + A) and (I - A/2) and indeed it equals I. That's it!? That proves it ?

Hello, I need a hint on how to begin this proof, please. Prove that if A is a projection matrix, A2=A, then I + A is invertible and (I + A) -1 = I - \frac{1}{2}A.

oh, forgot about that. thanks

it should have been http://latex.codecogs.com/gif.latex?e^{-i2x} so the latter expansion is correct.

here's my work in details, http://img811.imageshack.us/img811/7444/exsol.jpg"

Hello, I need to simplify and find Re and I am of . I've multiplied by and got that Re= and Im=. Is that the correct way and a correct result ?

I understand now, thank you all

i understand the mathematical formulas, but i wasn't sure about the meaning. so, correct me if I'm wrong: for functions like where http://latex.codecogs.com/gif.latex?|x|%3C1, in order to approximate the function at some point greater than one, i.e. x=3.5, i need to develop taylor series for...

Hello, if I understand correctly the Taylor approximation for a=0 gives me the possibility to approximate a function, say sin(x), at any x. But, what gives me Taylor polynomial at some point http://latex.codecogs.com/gif.latex?a\neq0 ,[/URL] what's the difference? what does it mean centred...
