$x = k π, k$ $x = kpi, k$ any integer

Explanation:

$tan x sec x = 0$ $tanx secx=0$
$\frac{sin x}{cos x} \times \frac{1}{cos x} = 0$ $sinx/cosx xx 1/cosx=0$
$\frac{sin x}{{cos}^{2} x} = 0$ $sinx/cos^2 x = 0$
$sin x = 0$ $sinx = 0$
$x = k π, k$ $x = kpi, k$ any integer

$x=kpi, kinZZ$

Explanation:

If $tan(x) * sec(x)=0$
then
$color(white)("XXX") {: (tan(x)=0," or ",sec(x)=0), (rarr x" is a multiple of "pi,,"not true for any real value of "x) :}$

Here is a graph with $color(green)(tan(x))$ and $color(red)(sec(x))$ for verification:
