Question

which of the following is a solution for the equation 1/485 tan^2x=0

a) no solution

b) 485 pi

c) pi

d) pi/2

I'm getting conflicting answers when I try to solve it.

Answer 1

1/485 tan^2x=0
tan^2 x = 0
tanx = 0
so x = π , 2π, 3π, .... , 385π
x = kπ, where k is any integer

so b) and c)
