## Mapple 16 mathematical function...

Maple 16

hello. before I used Mapple 15. But then I`ve run Mapple 16 and now I`ve a problem. I can`t use this program. I open the program, everthing is in the rule, but if I want to write any mathemathical function, or a letter, such as- x or x+2, the program does`t give any reaction. program only gives reaction the numbers.

Please, help me. (my english isn`t very good, and I don`t know I`ve explained my opinion).

## I need your help again...

Hello!

1)Dr:=[[1,5],[2,6],[3,4],[4,5],[5,7],[6,8],[7,4],[8,6],[9,5],[10,7]]:

2)Y:=proc(i) Dr[i,2] end;ty:=proc(i) Dr[i,1] end;

3)P[X](omega)=(1/2)*{(Sum(Y(j)*cos(omega*(ty(j)-1/(2*omega*tan((Sum(sin(2*omega*ty(j)),j=1..N[0]))/(Sum(cos(2*omega*ty(j)),j=1..N[0]))))))^2,j=1..N[0]))/(Sum(cos(omega*(ty(j)-1/(2*omega*tan((Sum(sin(2*omega*ty(j)),j = 1..N[0]))/(Sum(cos(2*omega*ty(j)),j=1..N[0]))))))^2,j= 1..N[0]))+(Sum(Y(j)*sin(omega*(ty(j)-1/(2*omega*tan((Sum(sin(2*omega*ty(j...

Hello, everbody!

1)Dr:=[[1,5],[2,6],[4,7]];

2)Y:=proc(i) Dr[i,2] end proc

3)ty:=proc(i) Dr[i,1] end proc

4)P[X](omega) = (1/2)*{(Sum(Y(j)*cos(omega*(ty(j)-1/(2*omega*tan((Sum(sin(2*omega*ty(j)), j = 1 .. N[0]));

1, 2, and 3 are known. I want to count 4, but I don`t know how I have to do this. Please help me.

Thanks...

## Can you help me for solving this ......

Maple

Hello everbody! Please, I need your help again.

B(ν)=2hν3/(c2 *(exp(hν/kT)-1);

h=6.63*10-34;

c=3*108;

k=1.38*10-23;

ν=0,001..10 if T=3000;

ν=10..10000 if T=3000;

plot(B(ν),ν);

Thanks

## How do I solve the following equations...

Hello, everybody! I can`t solve these equations. Please, help me! Thanks...

x=a*sin(k*z)±W/2;

k=2π/λ, λ=10000, a=3000, W=500;

and

x=z*tan(θ)-d*cos(θ);

θ=π/6, d=0..100;
