2sin45^(@)cos45^(@)

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

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

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

If a sin45^(@).cos45^(@).tan60^(@)=tan^(2)45^(@)-cos60^(@) , then find the value of a .

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

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

The value of ("sin"23^(@)"cos"67^(@)"tan"45^(@)+"cos"23^(@)"sin"67^(@)"cot"45^(@))/(2"sin"45^(@)"cos"45^(@)) is:

Find (in each case, given below) the value of x, if : sin 2 x = 2 sin 45^(@) cos 45^(@)

sin 45^(@)(cos 45^(@)) =…………..
