`cosec 45^(@)=`…….

Find the value of sqrt(cosec^(2) 45^(@) - cot^(2) 45^(@))

(tan45^(@)+cot45^(@))+(sec45^(@)cosec45^(@)) is …………………

Prove that : cosec^(2)45^(@)-cot^(2)45^(@)=1

Prove that : cosec^(2)45^(@)-cot^(2)45^(@)=1

Evaluate each of the following : tan60^(@)cosec^(2)45^(@)+sec^(2)60^(@)tan45^(@)

Evaluate each of the following :- (cosec^(2)45^(@)sec^(2)30^(@))(sin^(2)30^(@)+4cot^(2)45^(@)-sec^(2)60^(@))

If sec 3x = cosec(3x -45^@) , where 3x is an acute angle, then x is equal to: यदि sec 3x = cosec(3x -45^@) तो x का मान ज्ञात करें जहाँ 3x एक न्यून कोण है

( cos 45^ @)/( sec 30^@ + cosec 30 ^@) = ?
