`"cosec"^(2) 30^(@) cos 60^(@) tan^(3) 45^(@) sin^(2)90^(@) sec^(2) 45^(@) cot 30^(@) ` का मान ज्ञात करो ।

(2)/(3)(cos^(4)30^(@)-sin^(4)45^(@))-3(sin^(2)60^(@)-sec^(2)45^(@))+(1)/(4)cot^(2)30^(@)

The value of (sin^2 30^@+ cos^2 60^@+ sec 45^@.sin^2 45^@)/(sec60^@+ cosec 30^@) is : (sin^2 30^@+ cos^2 60^@+ sec 45^@.sin^2 45^@)/ (sec60^@+ cosec 30^@) का मान ज्ञात करें:

cos^(2)0^@-2cot^(2)30^(@)+3cosec^(2)90^(@)=2(sec^(2)45^(@)-tan^(2)60)

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

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

The value of (cosec 30^@-tan45^@) cot 60^@ tan30^@ is: (cosec 30^@-tan45^@) cot 60^@ tan30^@ का मान क्या है ?

The value of sin^2 42^@+ sin^2 48^@+ tan^2 60^@- cosec 30^@ is equal to : sin^2 42^@+ sin^2 48^@+ tan^2 60^@- cosec 30^@ का मान ज्ञात करें |

Calculate : sin^(2)45^(@)-"cosec"^(2)60^(@)+sec^(2)30^(@) .

The value of sin 0^(@) + cos 30^(@) - tan 45^(@) + cosec 60^(@) + cot 90^(@) is equal to
