[" If "tan^(^^)245^(@)-cosec^(^^)230^(@)=x sin45^(@)],[cos45^(@)" then "x=^(*)]

Choose the correct answer in each of the following questions: If tan^(2)45^(@)-cos^(2)30^(@)=x sin45^(@) cos 45^(@) " then " x =?

If tan^(2) 45^(@)-cos^(2) 60^(@)=x sin 45^(@) cos45^(@) tan 60^(@) , then find the value of x.

Evaluate sin45^(@)+cos45^(@)

4sin^(2)60^(@)+3tan^(2)30^(@)-8sin45^(@)*cos45^(@)

Value of sin45^@/cos45^@

" (iv) (sin30^(@)+tan45^(@)-cosec60)/(sec30^(@)+cos60^(@)+cot45^(@))

The value of sin45^(@)+cos45^(@) is :

Evaluate the following (sin 30^(@) +tan 45^(@) -cosec 60^(@) )/( cot 45^(@)+cos 60^(@) -sec 30^(@))

Evaluate the following (sin 30^(@) +tan 45^(@) -cosec 60^(@) )/( cot 45^(@)+cos 60^(@) -sec 30^(@))
