## Want to change the line style in loop...

Dearz

I draw multiple graphs in singal coordinate with same line style. I don't know how to change the line style and color for g[1], g[2] and g[3] becuase of loop. Please some fix my problem to give them different style and color.

## Need to simplify the expression ...

Dear all!

Hope everyone is fine with everything! I want to simplify the following expression

diff(u(y, t), t) = (A^2/nu)^(1/3)*nu*(diff(u(y, t), y, y))/(A/nu^2)^(2/3)-(A^2/nu)^(1/3)*sigma*B^2*u(y, t)/rho+(A^2/nu)^(1/3)*g*beta*q2[w]*sqrt(nu^2/A)*T(y, t)/((nu*A)^(1/3)*k)+(A^2/nu)^(1/3)*g*beta*T[infinity]/(nu*A)^(1/3)-(A^2/nu)^(1/3)*g*beta*V[infinity]/(nu*A)^(1/3)+(A^2/nu)^(1/3)*g*beta1*C(y, t)/(nu*A)^(1/3)-(A^2/nu)^(1/3)*g*beta1*C[infinity]/(nu*A)^(1/3)

I above the red terms need to simplify i.e., we can add the power of A, nu etc. But maple can't do that please fix my problem. For more detail I attach my maple file.

## Example using the product command...

How can i find the smallest n such that

using maple 2015?

I've tried using the solve command however this doesnt return a numerical value, any help would be great :)

## equation value display format ...

the final value of an equation is displayed in the form of combination of many values like following

-503.3433660*1[3]^2-2068.935708*1[4]^2-591.1244880*1[4]*1[1]-443.3433660*1[1]^2

I prefer to display it identically just an absolute value like 5.66

## Calculating an equation u(x,t) for all (x,t) from ...

Question:I've defined wave, but it's after that it gets sticky. This is my attempt:As you can see, not very fruitful. I have tried wave(x=-infinity..infinity, t=-infinity, infinity) which returns an error.

When i sub in wave(1,1) i get an answer, or any other number for that matter, but I'm not sure how to actually aswer this question.

Any and all help appreciated

Thank you

## Intersection of two curves using fsolve command...

Question: You will observe that the two curves intersect at one or more places in the displayed region. Use fsolve to find the (x; y) coordinates of all the points of intersection in this region.

In theory this question has a very simple answer, but i am struggling no end finding it.

P1 := y^2 = x^3+x^2

P2 := y = 2*x+1

This is what the graph looks like when plotted, and as we have already got the two equasions assigned as H and J, i just type in fsolve({P1,P2})?

Apparently not, as this returns {x = 4.048917340, y = 9.097834679}, which is correct, but is only one of three points of intersection, and just so happens to be the one not shown in my plot (although it is still a valid point of intersection) and i need the ones within the region i have set for the graph (x=-1..2 and y=-1..1).

How do i get maple to show me the two points of intersection i need using the fsolve command?

I've tried rearranging the equasions for y, rearranging for x, adding an option to solve for x [fsolve({P1,P2},x) but this returned an error] and am pretty stumped. For something so seemingly simple i dont really know where to turn.

Thank you :)

## How to use the product command in the following wa...

When i input: i get returned.and with this i have no idea what im supposed to do. I dont understand what it means, how to correct it or how to actually answer the question using the information.

This is what i am returned with when i try to input a sequence using my previous result.

Could someone please put me on the right tracks and help me with this problem?

Thank you

## How to construct a Matrix ?...

Hi,

Could you please help me in solving this problem ?

• N is the number of row, about 10^4 in real applications
• P is the number of columns (about 5)
• A and B are two NxP matrices
• C is the Nx(2P) matrix defined by
• its 2*k-1 th column is the k th column of A
• its 2*k th column is the k th column of B

What is the fastest and less memory consumming way to construct this matrix C ?
