## how to find equation of intersection between a pla...

Hi
i need to find equation of intersection between a plane(Z=0)  and 3d curve like below:

plane :  Z=0

curve:

sqrt(G*(2-G))+(1-G)*(arccos(G-1)+(1/5)*Pi)+k*sqrt(G*(2-G))*cos(sqrt((1+k)/k)*arccos(G-1)+(1/5)*Pi)+sqrt(k/(1+k))*(1-G)*k*sin(sqrt((1+k)/k)*arccos(G-1)+(1/5)*Pi)

I ploted Z=0 plane and that curve . it is like this .
i want equation of the pointed curve(curve equation of intersection between Z=  and curve )in bellow  such as k=f(G) .

best regards

## How to transform a function plot by "shifting" hor...

Hello,

I will explain my problem on a simple function and some data.

mg:=78.54*7.85*1e-9*1000*9.81;l:=10000;l0:=12000;h:=0;H := 28.399;
eta:=mg*l/(2*H);
zeta:=arcsinh(mg*h/(2*H*sinh(eta)))-eta;
z:=H/mg*(cosh(mg/H*x+zeta)-cosh(zeta));
plot(z,x=0..l);


Above is a definition of an initial plot. Now I would like to draw a new plot in which every x coordinate is shifted horizontally by a function:

deltax:=H*arcsinh(x)-x;

As you see I can't use translate or scale so I've tried to use a transform function but I can't do it the right way.

I would be grateful for any ideas.

Greetings,

Iza

## Why Simplify is working only for output labels and...

Hi, i will post the executed code so you can see what i am saying, essentially i want to know what i am doing wrong here to have simplify not work as a command line function but  it does when i right click the output and select it and the equation label of that output is inserted as the oprand.

I feel like maple is not wanting to be entirely forthcoming with me today or something, but in a more deeper contemplation, i see that refering to the maple interface as if it is a sentient entity is a true indication that i need a social life.

But as you will see, the same failure occurs for the ListTools partial sums feature when implemented in commandline code, but works perfectly well when it is selected by right clicking on the output intended

## How do I solve for the real part of a variable?...

Hi

I am trying to solve an inequality for the real parts of the solution to be less than 0. How do I do that? When trying to use solve, and specifying Re() Maple warns about lost solutions. I can see there are complex solutions to the equation, but i cannot make Maple calculate them. Maple gives me a range for the real solutions (6.1.11) and (6.1.12), but if I use a number out of the range the inequality is still met, the solutions is just complex, which does not matter. The variable a seems to be able to be between -8 and 3 for the real part of the solution to be less than 0.

Kind regards

Simon

## How do I define a vector from its angle and length...

hey guys does anybody know if i can define a vector from its degree and lenght. instead of having to use coordinates?

the only way i know of defining a vector so far is

Vector1:=<x,y>

sorry my english is'nt the best
