Run Example
```(%i1)plot3d(exp(-(x^2+y^2)/25)+exp(-((x-2)^2+(y-2)^2)/25),[x,-4,4],[y,-4,4]);
plot```
Run Example
```p(j,k):=(j+k)/j;
j + k
(%o1)                          p(j, k) := -----
j
(%i2) log2(x):=log(x)/log(2);
log(x)
(%o2)                          log2(x) := ------
log(2)
(%i3) eye(a,b):=(1/p(a,b))*log2(p(a,b))+(1/p(b,a))*log2(p(b,a));
1                       1
(%o3)     eye(a, b) := ------- log2(p(a, b)) + ------- log2(p(b, a))
p(a, b)                 p(b, a)
(%i4) plot3d(eye(a,b),[a,0,10],[b,0,exp(5)]);
plot```
Run Example
```plot3d(x*((exp(-x)-exp(-y))/(y-x)),[x,6.9,7],[y,6.9,7]);
plot```
