`2sin^(2)(pi/6)+cosec((7 pi)/6)cos^(2)(pi/3)=?`

2(sin^(2)(pi/6)) +"cosec"(7pi)/(6)cos^(2)pi/3=3/2

Prove that: 2sin^(2)(pi)/(6)+csc^(2)(7 pi)/(6)cos^(2)(pi)/(3)=(3)/(2)

2sin^2(pi/6 )+c o s e c^2((7pi)/6)cos^2(pi/3)=3/2

Prove that: (a) 2sin^(2)(pi/2) + "cosec"^(2)((7pi)/2) cos^(2)(pi/3)=(3/2)^2 (b) 2sin^(2)((3pi)/4)+2cos^(2)(pi/4)+2sec^(2)(pi/3)=10

(cot^(2)(pi)/(6)+csc(5 pi)/(6)+3tan^(2)(7 pi)/(6))/(2cos^(2)(pi)/(3)+csc^(2)(7 pi)/(6)*cot^(2)(pi)/(3)) is equal to

2sin^(2)((pi)/(6))+cos ec^(2)(7(pi)/(6))(cos^(2)pi)/(3)=(3)/(2)

Prove that (a) sin^(2)(pi/6) + cos^(2)( pi/3) - tan^(2)(pi/4) = -1/2 (b) sin((8pi)/3) cos((23pi)/6) + cos((13pi)/3) sin((35pi)/6) = 1/2

(sec^(2)(pi)/(4)-cot^(2)(pi)/(4))/(sin^(2)(pi)/(3)+cos^(2)(pi)/(6))+(sin^(2)(pi)/(2)-cos^(2)(pi)/(3))/((1)/(4)tan^(2)(pi)/(6))=9(2)/(3)

" 1.Prove that : "sin^(2)(pi)/(6)+cos^(2)(pi)/(3)-tan^(2)(pi)/(4)=-(1)/(2)

Find the value of the :cos^(2)((pi)/(6))+cos ec(5(pi)/(6))+3tan^(2)((pi)/(6))
