2sin45^(@)cos45^(@)

What is the value of sin^2 45^@+ cos^2 45^@ ? sin^2 45^@+ cos^2 45^@ का मान क्या है ?

cos^(2) 45^(@) - sin^(2) 15^(@)=

The value of (5cos^2 60^@+4sec^2 30^@-tan^2 45^@)/(tan^2 60^@- sin^2 30^@-cos^2 45^@) is: (5cos^2 60^@+4sec^2 30^@-tan^2 45^@)/(tan^2 60^@- sin^2 30^@-cos^2 45^@) का मान क्या होगा ?

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

The value of (cosec^2 30^@ sin^2 45^@ +sec^2 60^@)/(tan60^@ cosec^2 45^@- sec^2 60^@ tan45^@) is: (cosec^2 30^@ sin^2 45^@ +sec^2 60^@)/(tan60^@ cosec^2 45^@- sec^2 60^@ tan45^@) का मान है:

sin 45^(@)(cos 45^(@)) =…………..

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