Sin48° × sec42° + cos48° × cosec48° = 2

1.	Sin48° × sec42° + cos48° × cosec48° = 2
Answer» Answer :............... ___sin 48• × sec( 90•-48•) + cos ( 90•- 48•) × cosec 48• =........___sin 48• ×cosec 48• + sin 48• × cosec48•= 2............___1+1 =2 :::::Hence LHS = RHS I think there is a mistake in the question.....It can be....... Sin 48•× sec 42• + cos 42•× cosec 48• = 2
