Given an n*n matrix M an its rth row and cth column element m[r,c].Suppose m[r,c] = c*m[r-1,c]+a*m[r-1,c-1] and m[0,0]=1, m[0,k]=m[l,0]=0 for k>0,l>0.The letter "a" denotes a constant number and n can be any non negtive integer.

In 2D, graph a blue ellipse x(t)=3cos(t), y(t)=2sin(t) for 0≤t≤2∏. For t=0.5 graph a green tangent line to the ellipse and a red osculating circle. Also, give the curvature, the equation of the tangent line and the center of the osculating circle

Hi,

I have this system of lienar equations:

graph a red bezier curve start at the point P1(0, 0, 1) in the direction of <-2, 0, 1> and ends at P3=(0, 2, 0) from the direction of <0, 1, 0>. Use "axes=normal" and rotate the image for a good view of the curve. Also, write the coordinates of the other two control points that you used.

Hello,

for my mechanical engineering studies we have to optimize an engine during a workshop. Therefore we have to use a numerical dsolve to solve the equation of motion. I have to get the maximum bearing reaction for a constant rpm. In order to get this I can't think of anything else but use the dsolve solution and use it in maximize.

ysk_2 := t -> -rc*cos(phi(t))-lp*cos(alpha(t))-lkb-y(t);ysp_2 := t -> -rc*cos(phi(t))-lp2*cos(alpha(t))-y(t);

I have a Mma code from a colleague that I am trying to port to Maple. This code uses a lot of Mma With[{...}, ...] constructs, to which I found the Maple "use ... in ... end use" construct the closest equivalent. What is being done is to initialize a bunch of local variables and then run the calculations. Non-initialized variables (the ones not in the first section) remain global.

I ran into a problem in Maple when I tried to initialize an element of a Vector, like "use a[1...

i'm using maple 15 and trying to solve the following PDE without success, can you help please.

(ab+(a*sin(x1))^2-(c*cos(x1))^2)*d/dx1(V(x1,x2))=-dsin(x1)/exp(x1).

where a,b,c and d are constants. and i need it to be solved as a PDE please.

thank you,

My work requires me to use derivative a lot. Especially, the partial one. Given F(x,x_dot). Maple has this partial expression, however I'd like to partial differentiate F with regard to x_dot (the derivative of x over time).

Is this possible? If possible, please tell me how.

Thank you.

I was using the Finance package and used the command ImpliedVolatilitySurface(...). But it is showing the following error "Error, (in Finance:-ImpliedVolatilitySurface) external linking: error loading external library finance.dll: The specified module could not be found."Please help..

In geometry (2D), the triangle ABC has centroid is G(1, 1) and orthocenter is H(1,1). How to find the vertices A, B, C with the coordinates of this vertices are integers number?

what is the maple coding for the function, f(t)=-1-(epsilon)v(t) with the initial condition v(0)=1 for the 10 term?i had did it but i don't know how to come up with the expansion series in the maple coding
