`(sin(-(11pi)/3)*sec(-(7pi)/3))/(cot((5pi)/4)c o s e c((7pi)/4))=`

(tan(35pi//6)*sin(-11pi//3)*sec(-7pi//3))/(cot(5pi//4)*"cosec"(7pi//4)*cos(17pi//6))=

Prove that (sin(-(11pi)/(3))tan((35pi)/(6))sec(-(7pi)/(3)))/(cos((5pi)/(4))cosc((7pi)/(4))cos((17pi)/(6)))= (2)/(sqrt(3))

( sin (15pi//9)*tan(4pi//3)*sec(-7pi//3))/(cot(-3pi//4)*cos(7pi//6)*"cosec"(-7pi//4))=

Prove that, 3sin((pi)/(6))sec((pi)/(3))-4sin((5pi)/(6))cot((pi)/(4))=1 .

sin((7 pi)/(4))*cos((7 pi)/(6))*tan((3 pi)/(4))*cot((11 pi)/(6)) is equal to

sin((pi)/(16))sin((3pi)/(16))sin((5pi)/(16))sin((7pi)/(16))= ………..

cos ((5pi)/(4)) - sin ((5pi)/(4)) + tan((11pi)/(4)) - cot((11pi)/(4))=

Prove that, 3sin""(pi)/(6)sec""(pi)/(3)-4sin""(5pi)/(6)cot""(pi)/(4)=1
