which of the following are solutions of the equation tan^2x-1=0 check all that apply a) pi/4 b) pi/2 c) -pi/2 d)3pi/4

a

Step-by-step explanation:

tan^2x-1=0

tan^2x=1

tan x = +1 or -1

x= tan^-1 (1) or x= tan^-1 (1)

x= pi/4  or x= -pi/4

A and D

Step-by-step explanation:

just did it

0 is its x and y coordinate

correct answer is option b.

step-by-step explanation:

the true statement about geometric figure is option b that is one line can be drawn through all three points.

if three points are on the same plane, they can be connected by a line.
