How do you solve $-3x^3 + 7x^2 -14x + 8 = 0$?
It's a characteristic polynomial. Is it possible to solve it from here or must I solve them without opening too many brackets?

Let $f(t)= e^{t^2/2}$
by taylor series: $f(t)= \sum\limits_{j = 0}^\infty \frac{(t^2/2)^j}{j!}$= $\sum\limits_{j = 0}^\infty \frac{t^{2j}}{2^jj!}$

I can't get a clear graph on here, but you can graph it on a graphing calculator, the graph of the curve with equation: y=e^(2x)cosx
On this graph, P(a,b) is labelled in the first quadrant as ... | 4 | [

Find interval of function
Inflection points occur where $f\prime \prime (x) = 0$ If $f\prime \prime (x) = 0$ at $x = -1$ and $x = 3$, for example, then your intervals are $( - \infty , - 1), ( - 1,3), (3, + \infty )$ You can
determine the concavity of an interval by checking any value within that interval using $f\prim... | 4 | [
