Question

sec(X) +tan(x)=0

Answer 1

sec(x)=1/cos(x)
tan(x)=sinx(x)/cos(x)
1/cos(x)+sin(x)/cos(x)
(1+sin(x))/cos(x)

Answer 2

they say it has no sol. why??? @AJ01

Answer 3

is it true?

Answer 4

is there an angle that makes it zero

Answer 5

(1+sin(x))/cos(x)=0, to make this =0, sin(x) has to equal =-1 => x=270 but cos (270)=0
=0/0 undefined
