cot@+tan@=cosec@•sec@​

Answer 1

Step-by-step explanation:

I proved it step by step ok!

Answer 2

Answer:

easy

Step-by-step explanation:

write cot as 1/tan

$\cot( \alpha ) = \frac{1}{ \tan( \alpha ) }$

now just add it

$\frac{1}{ \tan( \alpha ) } + \tan( \alpha )$

we get

$\frac{1 + { \tan( \alpha ) }^{2} }{ \tan( \alpha ) }$

it is equal to

$\frac{ { \sec( \alpha ) }^{2} }{ \tan( \alpha ) }$

tan can be written as sin/cos
