Find the value of the following (i) tan 60^@ xx cos 30^@ (ii) sin 45^@ * cos 45^@ – sin^2 30^@ (iii) 2 sin 45^@* cos 45^@*tan 45^@ (iv) cos 30^@* cos 45^@ – sin 30^@* sin 45^@ (v) tan 30^@* sec 45^@ + tan 60^@* sec 30^@

If (2tan^(2)30^(@))/(1-tan^(2)30^(@))+sec^(2)45^(@)-sec^(2)0^(@)=xsec60^(@) , then the value of x is

sin60^(@)*sec^(2)45^(@)-3tan30^(@).4sin60^(@)=

Prove that : (2tan^(2)30^(@))/(1-tan^(2)30^(@))+sec^(2)45^(@)-cot^(2)45^(@)=sec60^(@) .

Evaluate : (cos^(2)(45^(@) + theta)+ cos^(2) (45^(@) -theta))/(tan(60^(@) + theta) xx tan(30^(@) - theta))+(cot30^(@) + sin 90^(@))xx (tan60^(@) -sec0^(@))
