`(tan 30^@cosec 60^@ + tan 60^@ sec 30^@) =? `

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 :

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

Solve: x tan 60^@cos^2 30^@ = (tan^2 45^@ sec 60^@)/(cosec 60^@)

IF x sin 45^@ cos ^2 60^@ = ( tan ^2 60^@ "cosec " 30^@)/(sec 45^@ cot^2 30^@) then x=

Find the value of: (tan 60^@- tan 30^@)/(1+ tan60^@ tan 30^@)+cos 60^@ cos30^@+ sin 60^@ sin30^@ .

Prove that : cosec 60^@ cot 30^@ tan 60^@= 2 sec^2 45^@ cos30^@ .
