If you stop losses at 2%, you'll be selling shares all the time, taking tax hits when you do, and having a hard time getting back in before the market moves back up.

Most retail investors get caught in these "strategies" and end up doing worse than the broad market.

Suggest that whenever your 2% stop loss strategy frees up cash from an individual stock , put half the money in a Large Cap index fund and the other half in a Mid Cap index fund, and then leave it alone.

If you want to start trading from home than you can use NinjaTrader.

I am suggesting you this because I have started my trading career from Ninja Trader only. And this is best and free application for trading from my experience.

The maximum value of the sine function is positive one, the minimum value is negative one. Within any limited range the maximum and minimum will fall between the two extremes.

If you have a graphing calculator, the easiest way to to find the maximum and minimum values of a sine curve is to plot it. Some calculators will even automatically find the max and min values. Others you'll have to eyeball it.

If you don't have a graphing calculator, you can calculate the value at a series of points and hone in the max and min values.

If you need further assistance, please reply to this post and specify the make and model of your calculator.

Hello,

When you are use the calculator to find a maximum or a minimum, you are supposed to give the calculator a range of values between which to search for i (interval where the max or min lies)

1.Look at the graph to locate approximately the position (the x coordinate) of the minimum.

2. Supply the left limit of x ( to the left of the minimum) Press [ENTER]

3. Supply the right limit of x (to the right of the minimum). Press [ENTER]

3. Supply an estimate of the X-value of the minimum.

After a moment the calculator displays the X and Y values of the maximum. The better your estimate, the faster the maximum will be found.

Hope this will help you set your problem correctly.

Hello,

I take your word for it. If graph is out of range you should zoom out.

But first try [ZOOM][6:Ztandard]. If you still see nothing, press [WNIDOW] and set XMIN=-100, XMAX=100, YMIN=-100, YMAX=100.

Otherwise you must know a few things about the behavior of the function you try to hraph

1. If X is always positif, set XMIN=0

2.If X is always negative, set XMAX=0

3. If Y has only positive values, set YMIN=0

4. If Y has only negative values, set YMAX=0

You can also calculate Y for X=0. Let Y(0) be that value. Then you try to have the Y-Values centerd around it: YMIN=Y(0)-10 and YMAX=Y(0)+10.

Hope it helps.

Hello,

I assume that by anti-derivative you mean the integral. I believe that you can only calculate definite integrals with this calculator. A definite integral requires that you specify the function e.g ln(x), the variable, x, the numerical value of the lower limit, 0.5 and the numerical value of the upper limit , say 2.

Try this:**INT(sin(x),x, 0, pi/2)**

This calculator can only give numerical values of definite integrals. If you want to perform symbolic calculations, you shoul look towards some other, more sophisticated Casios Casio ClassPad 330, or the TI Voyage200PLT, or the TI89Titanium. etc.

Hello,

Here how you do it taking as exemples y1=x^3 -5 and y2=abs(x^3-5)

Turn calculator ON by pressing [AC/On] . Use arrows to select [Graph] icon and press [EXE]

On line Y1= enter X[^]3 -5 [EXE]

On line Y2= press [OPTN] [F5:NUM][F1:abs] [(] X [^]3 -5 [)] [EXE]

The graphs will be drawn one after the other. You might have to adjust the window limits.

Here is an ouput drawn on another calculator.

For negative values of the x-variable, Y1 has negative values, while in the same range, Y2 has positive values, equal and opposite to those of Y1. In that range, Y1 and Y2 are symetric of each other with respect to the X axis.

For positive values of the x-variable, Y1 and Y2 are identical.

Hope it helps

Hello,

This calculator can only perform NUMERICAL DEFINITE integrals. Which meansyou have to supply the numerical value of the lower limit and the numerical value of the upper limit. The result is a numerical value.

The calculator cannot perform symbolic calculus.

If the function is simple you find the integral in tables of integrals where you will see that INT(log(X)dx=x(log(x)+1). Some calculators that have a CAS (computer algebra system) can manipulate symbolic expression, but not theCasio FX-991ES.

You ask it the value of the integral of log(X) from X=1 to X=3 and it will give you 0.5627748004

Hope it helps
