Question

Bhai teesri baar puchh rha hun jwaab de do prove that (cosec 0 - sec 0)(cot 0-tan 0)= (cosec 0+ sec 0)(sec 0 cosec 0-2)
and pls. no spamming​
and if you don't know the answer do not try to​
or spam krne wale ko usi time report kr diya jaayega​

Answer 1

Answer:

Taking LHS

= (1/sin0 - 1/cos 0) (cos 0/sin 0 - sin 0/cos 0)

= (cos 0 - sin 0/sin0cos0) (cos^20 - sin^20/sin0cos0)

=([cos0-sin0]^2/sin0cos0) (cos0 + sin0/sin0cos0)

=[1-2-cos0sin0]/sin0cos0) (cos0sin0/sin0cos0)

= (cosec0 + sec 0) (sec0 +cosec0 -2)

= RHS

Hope this helped you buddy.
