### [abs,cos,plot3d,sin,sqrt]

Run Example
```(%i1)f(x,y):= abs(2*x*cos(y)-sqrt(1-(2*x*sin(y))^2))/(1+2*x);
!                                  2 !
!2 x cos(y) - sqrt(1 - (2 x sin(y)) )!
(%o1)          f(x, y) := --------------------------------------
1 + 2 x
(%i2) plot3d(f(x,y), [x,0,5], [y,0,6.29]);
plot```
Run Example
```f(x,y):= abs(abs(sin(x)/(1-cos(x)))-abs(sin(y)/(1-cos(y))))/(sqrt(1+abs(sin(x)/(1-cos(x)))^2)*sqrt(1+abs(sin(y)/(1-cos(y)))^2));
!!  sin(x)  !   !  sin(y)  !!
!!----------! - !----------!!
!!1 - cos(x)!   !1 - cos(y)!!
(%o1)     f(x, y) := -----------------------------------------------

!1 - cos(x)!            !1 - cos(y)!
(%i2) plot3d(f(x,y), [x,3.141593/3,2*3.141593], [y,3.141593/3,2*3.141593]);
plot```
Run Example
```f(x,y):= sin(x)+cos(y) + sqrt(abs(x+y));
(%o1)            f(x, y) := sin(x) + cos(y) + sqrt(abs(x + y))
(%i2) plot3d(f(x,y), [x,-10,10], [y,-10,10]);
