> Diff(arccos(x^2+1),x);

d 2 ---- arccos(x + 1) dx

now is this ok? Are we getting the correct formating?? |

> plot(x^2,x=-1..1);

The following should show the image in reverse |

> Diff(arccos(tan(x^2+1)),x) = diff(arccos(tan(x^2+1)),x);

2 2 d 2 (1 + tan(x + 1) ) x ---- arccos(tan(x + 1)) = - 2 --------------------- dx 2 2 1/2 (1 - tan(x + 1) )
