Convert the following angle from radian to degree (pi)/(4)"rad"

Convert pi//6 rad to degrees.

Convert pi//6 rad to degrees.

Find the value of the following :- {:((a)sin((pi)/(6)),(b)cos ((pi)/(4))), ((c)tan((pi)/(3)),(d)cos ((pi)/(2))), ((e)cot ((3pi)/(4)),(f)sin((5pi)/(6))),((g)sin pi,(h)cos pi),((i)sin((pi)/(2)),(j)sin((3pi)/(2))),((k)cos((3pi)/(2)),):}

Evalute : "sin"^(2)(pi)/(4) + "cos"^(2) (3pi)/(4)+"cos"^(2)(5pi)/(4)+"sin"^(2)(7pi)/(4).

cos^(-1)((cos(7 pi))/(6)) is equal to ( a ) (7 pi)/(6) (B) (5 pi)/(6) (C) (pi)/(3)(D)(pi)/(6)

"sin"^(4)(pi)/(16) + "sin"^(4) (3pi)/(16) + "sin"^(4) (5pi)/(16) + "sin"^(4) (7pi)/(16)=

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