Question

Can anybody tell
what is tan-1(xy)= ?

Answer 1

It depends on what value x and y are.

Answer 2

what is the value of (xy)?

Answer 3

can we find in term of x and y an expression? what do you mean by value of x and y?....... My objective is to simplify it so that i can use x and y in further simplification

Answer 4

i could't found tan(xy) as well.........this is not standard identity but there must be a simplified form, in terms of x and y

Answer 5

okay! so tan-1 is -0.017

Answer 6

i didn`t understand your question very well!

Answer 7

as tan (a+b) can be written as simplified form, what could be the form of tan-1(xy)

Answer 8

I don't think there is simplified form for \(\tan^{-1}(xy)\)
