" Change in Cartesian form of "sqrt(2)(cos45^(@)+sin45^(@))" is "

cos 45^(@)-sin 45^(@)=?

2sin45^(@)cos45^(@)

The value of cos45^(@)-sin45^(@) will be :

Prove sin A+cos A=sqrt(2)cos (45^@-A)

sin^(2)45^(@)+cos^(2)45^(@)=

(cos 45^(@))=1/(sqrt(2))

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

Find the value of (sin45^(@) + cos 45^(@))

Given that (2 sqrt3 cos 30^(@) - 2i sin 30^(@))/(sqrt2 (cos 45^(@) + isin 45^(@)))=A + Bi , find the values of A and B.

Find the value of (cos(45^@-A))/(sin(45^@+A))
