Question

sec(x)+tan(x)=0
why does it have no solution?

Answer 1

because,
sec(x) + tan(x) = 1

1/cos(x) + sin(x)/cos(x) = 1

(1 + sin(x)) / cos(x) = 1

1 + sin(x) = cos(x)

1 = cos(x) - sin(x)


x = 0 radians, 2π, 4π ... 2nπ radians

Answer 2

but the equation is equal to zero but your's is equal to one?

Answer 3

can u understand this?
