Say I have a polynomial x^5 + 4xy^4 + 2y^3 + x*y^2 + x^2 + y + 3

Can I truncate it up to total degree 3 (for example), so 2y^3 + x*y^2 + x^2 + y + 3

Dear Readers,

Given an expression for e.g. x^n+ y^3.5, how to extract the symbolic/floating point exponent, I tried with degree method but it fails whenvever there is symbolic or floating point exponent. Is there any alternative ?

Thanks,

Dear everyone,

Hello,

I have a question about how to get the power 'n' in an expression "(x+y)^n". For instance, I have a Maple code

******

eq1:=4*x^n*y^m+(x+y)^n+x^3;f1:=map(t -> `if`(match(t = c*y^d, y, 's'), subs(s,d), NULL), convert(eq1, list));f2:=map(t -> `if`(match(t = c*x^d, x, 's'), subs(s,d), NULL), convert(eq1, list));

Hey there,

i have an System in the form below.

I try to plot s over the angle t which is used in the functions (S,DS and DDS) but because maple uses t in the functions (s, v and a) as the time the calculated eigenfrequency doesnt fit to the System.

The eigenfrequency should be omega:=sqrt(c[0]/m[1])=1035 (over 360 degrees) but because of the angle time switch the eigefrequency is 1035 (over 1).

Has someone an idea how i can tell maple that t is an angle in degree? ...

> seconddegree:= proc(a,b,c)

if a=0 then if b=0 and c=0 then print ('infinite solutions')

elif b=0 and c<>0 then print ('impossible')

elif b<>0 and c<>0 then print (' one solution',x=-(c)/(b))fi;

delta:=b^(2)-4 *a*c;

elif if delta=0 then print('double solution',x=-b/(2 a))

elif delta >0 then print ('exist two solutions',x1=((-b+sqrt(delta...

I have to generate F(x) of a function with a degree of 5 who has zeros of x=2,x=1+3i,x=2-4i

After i put it into maple i use the command expand to give me the total function but afterwards i get this 144*i^4*x-25*i^2*x^3+x^5-288*i^4+118*i^2*x^2-8*x^4-188*i^2*x+25*x^3+104*i^2-38*x^2+28*x-8

i need to know what command can i use to get it to converts i^4 to 1 and i^2 to-1 that way i can truly simplify it.

Hello, I have a question about obtaining the power of a variable. Suppose

f:=x^5;

g:=degree(f,x);

I got 5.

now let f:=x^n;

g:=degree(f,x)

I got FAIL :( I tried g:=log[x](f), it doesn't go to "n" either.

Is there anyway I can simply get the "n" in x^n? I know "n" is an integer, but how to refine into integer type?

Thank you very much in advance

how can i solve the following ODE in degree and not in radiant... numerical solution is required... im allways getting the wrong eigenfrequency.

>m*D(D(x))(t)+d*D(x)(t)+k*x(t)=sin(2*t)

How to compute the highest total degree of a polynomial in which a variable, say x, appears?For example, f := x^2*y+3*x*y^2+x^3*y^3-x^5+y^4*z^5;then the highest total degree in x is 6.The degree command does not seem to do what I would like to do, since degree(f,x) will give 5 instead.Thank you in advance.
