arccot = cot ^-1 not 1/cot

Answer 2

so which one is arc cot on ti83plus?

Answer 3

\[1/\tan^{-1}( 7/22) = 3.25\]

Answer 4

for some reason the answer is 1.26 but I don't understand how to obtain this.

Answer 5

do 2nd tan and you will get arctan and when you put tan or arctan as 1/ tan (or arctan) you will get cot or arccot
