**
tan(x)= 1/cot(x) is true because the value one function is a reciprocal of the value of the other function.
For example, tan 30�=1/√3=√3/3
1/cot 30�=1/√3=√3/3
..
The inverses, however, are angles.
Using values for the inverses from the previous example:
tan^-1 (√3/3)=30�
1/cot^-1 (√3/3)=1/30�≠30�
Values of reciprocal functions are equal, but their inverses are not.
