I have something like E1:=y=x*b+z*a+c*i. and i want to solve for y/i. I try doing solve(E1,y/i) but it says i cant solve for an expression. is there a way to get around that?

for example:

>>simplify(cos(i)*sin(u)/sin(i),trig)

                    cos(i)*sin(u)/sin(i)

Maple do'not  simplify cos(i)/sin(i)=ctan(i) atomaticly.

also  half angle formulas:

>>simplify(sin(i)/(cos(i)+1),trig)

           sin(i)/(cos(i)+1)

i want to get tan(i/f)

Hi all, I found that the expression:

(2x+7)/5+(6x-3)/3

automatically simplifies to

Is there a function that will return

which is one fraction, instead?

I would like to simplify algebraic modulo expression.

For example, (N+k) mod N should be simplified to k mod N (N and k are positive integers).

Is there a way to achieve this with maple?

Thank you!

How can several expression statements be not displayed during and after an execution process of "then"conditional statement (I mean "If.....then...")?
For example:

each expression above can consist of various commands in its body.All my exp statements were finished by ":"

Hi all,

I've got the following Maple math code (its called the 'Strickler function', giving a relation between water hight 'y' in a channel and other paramaters), that works like a charm and correctly outputs my function Q =

> restart;
> A := (b+m*y)*y;
> R := A/(b+2*y*sqrt(1+m^2));
> Q := k*A*R^(2/3)*s^(1/2);

However, all contants in the functions are know, except for 'y' (Q is known as well). How do I solve the last equation for...

How can I get this expression, ln(1+y²/(x-1)²)+2ln(x-1) , to simplify to ln((x-1)²+y²) ?  I would think Maple should be able to do that.  Thanks, Ratch

Hi,

Does any body know how one could calculate such an integration:

Int(expression, 1/x)

Thank You!

Hello everyone. I am new to Maple. I am trying to simplify an expression in Maple. The expression is like:

u := a+b*x+a/x+b*x^7+c

If I use simplify(u) Maple returns the result as:

 (a*x+b*x^2+a+b*x^8+c*x)/x

If I want the result in the form:

u = a*(x+1)/x+b*x*(1+x^6)+c

or

u = a*(1+1/x)+b*x*(1+x^6)+c

How should I proceed? Is it possible to do this?

Suppose I have the following expression:

u=a+bx

Now I want to determine a and b using the conditions:

at x=h, u=4;

at x=6, du/dx=4.

Can I do the same using MAPLE? If possible how can I do it. Where to look for it?

Thanks in advance.

Hello

i want to simplify this expression (f@f@...@f@f)(x)

f is repeated "n" times

e.g: for n=3

we found (f@f@f)(x) .

help me please.

How may I program the following with Maple?

(1) Define the function:

H(p) := p * c1 + p^2 * c2 + p^3 * c3  + ......

(2) Now construct the following expression:

(1-p) [ v''' + 1 ]  = H(p) [ v''' - 25 * v' + 1]

Here, v is some funciton of x.

(3) Now assume: v = u0 + u1 * p + u2 * p^2 + ...

and substitute this into the expression defined at the point (2).

Wide set of expressions can convert to compiled functions. Expressions can even include definite integrals.
Hope it helps for others who want really speedup calculations in maple as much as possible for now.
