Hello,every one,i want to solve system of equations but i recieve an error ,how can i find the coeffecients c1,c2,c3,c4?thank.

Error, invalid input: too many and/or wrong type of arguments passed to SolveTools:-PolynomialSystem; first unused argument is {beta = 2, x = 1/5}

Hi,

Here is my question.

I am trying to substitute value of lambda(t-t1) further but it is not taking the value.

Thanks in advance.

#Hello people in Mapleprimes,

#After

restart;interface(typesetting=extended);

diff(f(x),x);

#shows f'(x).

#But,

diff(f(t1),t1);

#shows just df(t1)/dt1, not f'(t).

#Can't I show f'(t1) not df(t1)/dt1?

#Is this a way peculiar to Maple?

#I hope someone could give me some hints.

#Best wishes.

Hello,

I would like to know how one would add a superscript in maple? For example, I need to label an axis with unit cm^-1 but it shows 1/cm (like a fraction) when executed. How could I avoid this so the graph label would output cm^-1? Thank you for your help in advance!

Please how do I type accents in code edit region of maple 2015.1 (for instance putting "Hat over" on alpha)?

Thank you.

hello every one.please help me with solving this equations.i can not solve this and i need it.thanks

eq1 := (cos(beta2)-1)*w11-sin(beta2)*w12+(cos(alpha2)-1)*z11-sin(alpha2)*z12-cos(delta2) = 0; eq2 := (cos(beta2)-1)*w12+sin(beta2)*w11+(cos(alpha2)-1)*z12+sin(alpha2)*z11-2*sin(delta2) = 0; eq3 := (cos(beta3)-1)*w11-sin(beta3)*w12+(cos(alpha3)-1)*z11-sin(alpha3)*z12-3*cos(delta3) = 0; eq4 := (cos(beta3)-1)*w12+sin(beta3)*w11+(cos(alpha3)-1)*z12+sin(alpha3)*z11-4*sin(delta3) = 0; eq5 := (cos(beta4)-1)*w11-sin(beta4)*w12+(cos(alpha4)-1)*z11-sin(alpha4)*z12-5*cos(delta4) = 0; eq6 := (cos(beta4)-1)*w12+sin(beta4)*w11+(cos(alpha4)-1)*z12+sin(alpha4)*z11-6*sin(delta4) = 0; eq7 := (cos(beta5)-1)*w11-sin(beta5)*w12+(cos(alpha5)-1)*z11-sin(alpha5)*z12-7*cos(delta5) = 0; eq8 := (cos(beta5)-1)*w12+sin(beta5)*w11+(cos(alpha5)-1)*z12+sin(alpha5)*z11-8*sin(delta5) = 0; alpha2 := -20; alpha3 := -45; alpha4 := -75; alpha5 := -90; delta2 := 15.5; delta3 := -15.9829; delta4 := -13.6018; delta5 := -16.7388; P21 = .5217; P31 = 1.3421; P41 = 2.3116; P51 = 3.1780;

If I have a fraction like this w^2/(w^4+2*w^2+1) , how can I make it presented in Maple as '1/(w^2+1/w^2+2)' (Both numerator and denominator divided by w^2) ?

Thanks in advance!

When using units, then e.g. "2 m" is show as expected below, but "1 m" shown as only "m". Even through correct, it is a non-standard way to write physical values.

How to get the physical values in a format of "{numerical} {unit}" even when the numerical part is 1?

In a simple example below I try to write an equation with an unknown value present among other values that have unit, but I get an error since the unknown value d does not have a unit yet.

How to write such expressions, e.g. for use in solve later?

Dear MapleSoft,

Would it be possible you once design a MapleSim webinar for users with more emphasis on Modelica (language, examples, etc.), on how to build more complex custom components, not just a simple DC motor? I think this would be very useful and could extend / enhance the use of MapleSime even more.

Tx in advance,

best regards

you write:

In the code below the new function g is defined based on existing function f, but the new function g is then dependent on f at the time of definition, which is shown since later changes to f will change value of g.

How to fix definition of g based on f at the when g is defined, so later changes of f does not alter g ?

Hello every one,please help me for plotting this equation(T).L=1,t=10,a=0.1,x=0..1

hi
