There is a series of numbers denoted by a1, a2, a3, ... aX (Not in Arithmetic Progression!). Here's what we have:

a1 = 1
and
a(M + N) = aM + aN + MN

Using the two given data, find the 2001st term.





In case you have trouble understanding:
a1 is the first term, a2 is the second term and so on. aX is the xth term.
a(M + N) denotes the (M + N)th term of the series.

And remember that this is NOT an Arithmetic Progression!

lim_{n→c} f( g(n) ) = lim_{ u→[ lim_{n→c} g(n) ] } f(u)

The limit of the compound function f(g(n)), as n approaches c... is set equal to... the limit of the outer function f(u), as u approaches a value equal to the limit of the inner function g(n), as n approaches c.

To me, this makes sense logically. But I dont have a formal proof. And Im not certain on any stipulations.

Merry Christmas!!
I'm trying to finish my math homework,but I forgot the operations for some problems.
Could you include steps in how you found the answer?

4x^2+2x-3 - 2x^2-5x-3

Simplify:
(x-7)(x+3)-x^2+6

Solve for x:
(2^x) + (3^x) - (4^x) + (6^x) - (9^x) = 1

Pretty hard when x is the exponent isn't it?






This has nothing to do with the question, but can someone tell me how to get exponents easily here. I can copy-paste exponent numbers from Microsoft Word easily, but not exponent variables like x.
When I paste 2^x from Word, it looks like 2x here.
But 2² is still 2².

Let the function h be defined by h(x) = 14 + x^2 / 4 . If h(2m) = 9m, what is one possible value of m?


The answer is supposed to be either 2 or 7, but i can't seem to come to those answers. Please give me a step by step of how to get to those. Thanks alot

Shouldn't the derivative of this be (cosxtanx + sinxsec^2x)? My book says (cosxtanx+secxtanx). Why!?!? Am I missing a trig identity or something? I'm trying to learn calculus and it doesn't explain why at all! Please help and thanks in advance!

This goes against the order of operations. Aren't you supposed to multiply 6 by 3 first?

Or does the complementary rule only apply to two angles?
