Hello.I could use some help to solve the folowing system, please.

Basically I have the 4 unknowns (A,P,C2,alfa)and I want to know their values by changing values to "a2" (eg. varying a2 from [0;80]).

With another software I solved matricially the EQ2;EQ3 and EQ4 for P,A and C2 with different values of a2 and then I replaced the P,C2 solutions (for each a2 value) on the EQ1 and tooked the value of "alfa" for each corresponding "a2". At the final I had the 4 unknows solved varying the "a2" value.

Can I get a box plot on an x-y-z graph?

How do you do this?; actually, for starters, how do you display 2 plots side by side?


I have a problem with an assumed real variable that are not inserted into equations if it is given an nummeric value. I have tried to make and example below:

>A := e^(I*theta)

hi, suppose

integers:=[`$`(-10..10)]; selectremove(`<`,integers,0);

so this separates +ve and -ve. But, if the range of values are complex, how do we separate them based on the +ve and -ve of the real part of the complex number? i.e I want to separate all a +- bi from all -a +- bi.




My equation is the following:

Y = 1 - ( sin (2*theta)/ (X+cos(2*theta)))^2

where theta=20 degrees = pi/9  and X= 0..30. How can I numerically calculate Y as a function of X.  And also how can I plot Y(X),

Y(1/X)  and  Y(1/X^2). I like to do these for different theta values (i.e., theta=2*pi/9,  theta= 3*pi/9,,,,,, theta=4*pi/9 ).

Thank you in anvance


if i have ten "hz", each displayed with hz[i] was calculated before, then want to make a continues expression and plot it, i use this form and it answered me correcctly. piecewise(x <><><><><><><><><>
OK, so ive solved a pde numerically. I can plot the solution as a graph, evaluate the value at different times, but how can I integrate it over the region it is defined? My goal is this, the weighted average of x:

Can alone explain to me what is happening in this procedure? I know it is it is to generate a line p and an angle theta but don't understand what line and angle or how it does it.

Im having trouble with the DEplot command, i seem never to be able to use the plot commands on maple no matter what i do. Heres what i've got so far. > eq1 := diff(n(t), t)+lambda*n(t) = 0; / d \ |--- n(t)| + lambda n(t) = 0 \ dt / > eq2 := dsolve([subs(lambda = .1, eq1), n(0) = 10]); / 1 \ n(t) = 10 exp|- -- t| \ 10 / > with(DEtools);

In the help, it writes

BesselJ and BesselY are the Bessel functions of the first and second kinds, respectively. They satisfy Bessel's equation:
     2                2    2
    x  y'' + x y' + (x  - v ) y = 0

My problem is in statistics. I'm looking for the resulting normalized distribution funtion.

Given a sample has a normal distribution of trait A, and given a subgroup that posseses trait B with a different normal distribution of trait A. Waht would the distribution of trait A be if we eliminate the subgroup that posseses trait B.

The following example that assumes a subgroup of 20% does not yield the proper result.

f := x -> if(x<=0, 0, 1):

Why do the first two plots work, but the third and fourth doesn't? How do I plot the sum of this function in a specific range?

How do I get a closed-form expression?

I tried the following (e.g.):


> k[21] := t-> piecewise(t<0,0,p*(1-p)^t);                      {definition of descrete probability distribution, here: geometric distribution}

I want  to calculate the derivative of Bessel, I do
