2012-01-31 A problem:

Let the function be 3 - 5^(-x).  Let infinity be oo.    If we look at the lim(x->oo), the power of 5 goes to 0 and the answer goes to 3.  If we look at the lim(x->-oo), the power of 5 goes to oo.  Since

2012-01-21 The existence of a solution of 1st order ODE's:

Yes, it has been shown that a solution exists.  Look at  http://projecteuclid.org/DPubS?http://www.unf.edu/~mzhan/chapter2.pdf  to see that they may not be expressable in y = f(x).  This paper tells you

2012-01-06 Solving polynomial simultaneous equations using matrices:

Hello James,    The three data points you have slected give the three linear equations for a,b, and c.    For the RREF (Reduced Row Echelon Form) algorithm by using "elementary row operations"  check these

2011-12-21 Differentials:

I believe that last sentence is true.  If we have a function, f(x), if there is a df on one side of an equation, there needs to be a dx on the other side.  Both are usually found at the end of the expression

2011-12-14 Elasticity:

Elasticity has to do with the derivative at a point.    If the equation for quantity is Q = 7 + P + 0.0004P²,  then the elasticity at some value of P is given by dQ/dP.  From the equation, it can be seen
