The value of (cos^(2)33^(0)-cos^(2)57^(0))/(sin21^(0)-cos21^(0)) is

(cos^(2)33^(@)-cos^(2)57^(@))/(sin21^(@)-cos21^(@))=

The value of (cos24^(0))/(2tan33^(0)sin^(2)(57^(0)))+(sin162^(0))/(sin18^(0)-cos18^(0)tan9^(0))+cos162^(0) is equal to

Prove that: (cos^(2)33^(@)-cos^(2)57^(0))/((sin^(2)(21^(0)))/(2)-(sin^(2)(69^(0)))/(2))=-sqrt(2)

Without using trigonometric tables,evaluate each of the following: (sec^(2)54^(0)-cot^(2)36^(@))/(cos ec^(2)57^(0)-tan^(2)33^(0))+2sin^(2)38^(@)sec^(2)52^(0)-sin^(2)45^(@)

Evaluate: (sec^(2)(90^(@) - theta)-cot^(2) theta)/(2 (sin^(2) 25^(@)+sin^(2) 65^(@)))+(2 sin^(2)30^(@)tan^(2) 32^(@) tan^(2)58^(@))/(3(sec^(2)33^(@)-cot^(2)57^(@))) .

" If "sin^(2)1^(0)*sin^(2)3^(0)*sin^(2)5^(0)......sin^(2)89^(0)=m^(n)." Then "|m-n|=
