Hi, everybody!
I am a lover of maths and go crazy to solve any mathematical problem or to discuss any thing about maths. So please feel free to discuss with me.
Looking forward to getting any maths problem soon,

I have a trig word problem that has got me stuck. If you could help that would be great. The problem shows a diagram of a street light. The length of the base pole is 28.0ft, the length of the pole connected from base pole to street light is 12.5ft. The angle of the connected poles is 20.0 degrees. How high above the street is the light?
Thank you
3. One side of a triangle has length 8 and a second side has length 5. Which of the following could be the area of the triangle?
I 24
II 20
III 5
A. I only
B. II only
C. III only
D. II and III only
E. I, II and III
the answer is d i can get 20 by 1/2 base heigth . but can not figure out how to get 5?
Can you help with this assignment?
1 Goal
Download data on VIX futures from CBOE and construct a time series of 1-
month constant maturity futures by suitable interpolating and rolling over the
futures contracts.
2 Deliverable
An Excel workbook with all underlying data, and a daily time series of
1-month constant maturity futures based on
{ High
{ Low
{ Close
{ Settle
A document containing a description of the VIX futures contract: what
is the underlying, how is it computed, how is it settled etc.
3 Details
The above link contains links to data les for VIX futures from 2004 until now.
You will need to download all data les and process them. Observe that there
is a variety of maturity dates which you will need to consider. With suitably
rolling over I mean that if the maturity becomes to short, say less than 10 days
or a week you will need to switch to the next futures contract. You will need
to interpolate, since the futures contracts have standardized maturity dates,
and you will need to articially construct the constant maturity (1 month) by
interpolating between two adjacent maturity dates.
Hi neerajkarn, please help me solve these...
Millennium Prize Problems - Wikipedia, the free encyclopedia
i would like to prove that:
$\displaystyle (\zeta(z) = 0) \wedge (\text{Re}(z) > 0) \implies \text{Re}(z) = 1/2$
i need this fast! (gambling debts. these loan sharks are *so* not understanding my plight.) plz help. kthxbai.
(if you can give me a closed-form expression for $\displaystyle \zeta(3)$, that'll do as a stop-gap, but i need the first one more).
There are three ways you can evaluate the area of a triangle, namely $\displaystyle \displaystyle \begin{align*} A = \frac{1}{2}bh, A = \frac{1}{2}ab\sin{C} \end{align*}$ and $\displaystyle \displaystyle \begin{align*} A = \sqrt{s(s-a)(s-b)(s-c)} \end{align*}$, where $\displaystyle \displaystyle \begin{align*} s = \frac{a + b + c}{2} \end{align*}$.
If the area was $\displaystyle \displaystyle \begin{align*} 24 \end{align*}$, then it would be possible to have
$\displaystyle \displaystyle \begin{align*} 24 &= \frac{1}{2}\cdot 5\cdot 8 \cdot \sin{\theta} \textrm{ (where }\theta\textrm{ is the angle in between the two sides given)} \\ 24 &= 20\sin{\theta} \\ \sin{\theta} &= \frac{6}{5} \end{align*}$
This is impossible because $\displaystyle \displaystyle \begin{align*} -1 \leq \sin{\theta} \leq 1 \end{align*}$ for all $\displaystyle \displaystyle \begin{align*} \theta \end{align*}$.
Can you use a similar process to see if it's possible for $\displaystyle \displaystyle \begin{align*} 5 = \frac{1}{2}\cdot 5\cdot 8 \cdot \sin{\theta} \end{align*}$?
Let $\displaystyle \displaystyle \begin{align*} u = x^3 + 3 \end{align*}$ so that $\displaystyle \displaystyle \begin{align*} y = 6\cos{u} \end{align*}$. Then
$\displaystyle \displaystyle \begin{align*} \frac{du}{dx} &= 3x^2 \\ \\ \frac{dy}{du} &= -6\sin{u} \\ &= -6\sin{\left(x^3 + 3\right)} \\ \\ \frac{dy}{dx} &= \frac{du}{dx} \cdot \frac{dy}{du} \\ &= 3x^2 \left[-6\sin{\left(x^3 + 3\right)}\right] \\ &= -18x^2\sin{\left(x^3 + 3\right)} \end{align*}$
