+129839 tan^2x csc x=tan^2x rearrange as
tan^2x cscx - tan^2x = 0 factor
tan^2x (cscx - 1) = 0 set each factor to 0
tan^2x = 0 take the square root of both sdes
tan x = 0 and this occurs at n * pi where n is an integer
Also.....
cscx - 1 = 0 add 1 to both sides
cscx = 1 and this occurs at pi/2 + (n) * 2pi where n is an integer
