Answer 1

HELLO DEAR,


LET THETA=a
$\sec(a) \times \sin(a) = 0 \\ = > \frac{1}{ \cos(a) } \times \sin(a) = 0 \\ = > \tan(a) = 0 \\ = > \tan(a) = \tan(0) \\ = > a = 0$

I HOPE ITS HELP YOU DEAR,
THANKS

Answer 2

Step-by-step explanation:

HELLO DEAR,

$LET THETA=a</p><p>\begin{lgathered}\sec(a) \times \sin(a) = 0 \\ = > \frac{1}{ \cos(a) } \times \sin(a) = 0 \\ = > \tan(a) = 0 \\ = > \tan(a) = \tan(0) \\ = > a = 0\end{lgathered} </p><p>sec(a)×sin(a)=0</p><p>=> </p><p>cos(a)</p><p>1$

$×sin(a)=0</p><p>=>tan(a)=0</p><p>=>tan(a)=tan(0)</p><p>=>a=0$

I HOPE ITS HELP YOU DEAR,

THANKS
