Evaluate : (i) sin60^(@)*cos30^(@)-cos60^(@)*sin30^(@) (ii) tan30^(@)*cosec60^(@)+tan60^(@)*sec30^(@) .

(tan30^(@)cos ec60^(@)+tan60^(@)sec30^(@))=?

Evaluate each of the following : tan30^(@)sec45^(@)+tan60^(@)sec30^(@)

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^@

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

The value of (tan30^@ cosec 60^@+tan60^@ sec 30^@)/(sin^2 30^@+4cot^2 45^@-sec^2 60^@) is: (tan30^@ cosec 60^@+tan60^@ sec 30^@)/(sin^2 30^@+4cot^2 45^@-sec^2 60^@) का मान है :
