sec a -cos a× cot a + tan a = tan a sec a
Added by Ashley L.
Step 1
First, we can rewrite the given equation in terms of sine and cosine: $$ \frac{1}{\cos a} - \frac{\cos a}{\sin a} \times \frac{1}{\sin a} + \frac{\sin a}{\cos a} = \frac{\sin a}{\cos a} \times \frac{1}{\cos a} $$ Now, let's simplify the Show more…

$$ (\sin A+\cos A)(\cot A+\tan A)=\sec A+\operatorname{cosec} A $$
$$ \frac{\tan A}{1-\cot A}+\frac{\cot A}{1-\tan A}=\sec A \operatorname{cosec} A+1 $$
$$ \frac{\tan A+\sec A-1}{\tan A-\sec A+1}=\frac{1+\sin A}{\cos A} $$
