F O L L O W F O R N E W (a/e^a)^2 + (b/e^a)^2 = 1 [4] a^2 + b^2 = e^2a Okay so I have these 4 equations and I still can't find solutions to any of them, I only need to find a or b and the solution to e^x = x will follow. Could you please help? +I'm only a college student and haven't done much uni level maths, so go easy on me if I've missed something blindingly obvious.

Now consider a weightless rod on which are placed weights, at locations x i along the rod and having masses p i (whose sum is one). The point at which the rod balances is E[X]. The correct answer is e^ (2x). Just another way to think of it is when you multiply x * x you have x^1 * x^1 and your answer is x^ (1+1) = x^2 So e^x *e^x = e^ (x+x) = e^2x Like any other situation where you're multiplying two exponential expressions with the same base (in this case e), you add the exponents.

Let Z = X/Y. Find the pdf of Z. The ﬁrst thing we do is draw a picture of the support set (which in this case is the ﬁrst Functions like 1/x approach 0 as x approaches infinity. This is also true for 1/x 2 etc. A function such as x will approach infinity, as well as 2x, or x/9 and so on. Likewise functions with x 2 or x 3 etc will also approach infinity.
