Question

Find the values of the inverse function in radians.


tan^-1(0.09)

answer choices:

a.-0.09+2pi n
b. no such angle exists
c.-1.48+ pi n
d. -0.09+ pi n

My answer is D

Answer 1

tan .09 = .09

so, the solutions are .09 + nπ

I suspect a typo. Did you mean tan^-1(-.09) ?

and also on the last post?
