(iii)
tan , cote = 1+ secê coseco
1-cot 8 1 -tan
[Hint : Write the expression in terms of sin @ and cos 0]
1+ cot A sin ? A
sec A 1- cos A [Hint : Simplify LHS and RHS separatelyl
cos A- sin A +1
--- = cosec A+cot A using the identity cosec? A=1
cos A+ sin A-1
= tan
1+ sin A
1 - sin A
e A+tan A
sin - 2 sinB
COS - cos e
(vii)
(viii) (sin A+ cosec A)2 + (cos A + secA)2 = 7 + tanA+ cot? A
(ix) (cosec A - sin A)(sec A - cos A) =
tan A +cot A

Answer:

please repost the question again with required spaces and symbols as the question is not understandable and clear..

sorry but I will surely answer after you repost the question again..❣️

and ya only post 1 question at a time instead of posting 9-10 questions together in a question as sub-questions as no one would be interested in solving so many questions and that too of trigonometry
