(tan47^(@))/(cot 43^(@))=1

Evaluate: ((sin47o)/(cos43o))^(2)+((cos43o)/(sin47o))^(2)-4cos^(2)45o

The value of (sin 43^(@))/(cos 47^(@))+(cos 19^(@))/(sin 71^(@))-8cos^(2)60^(@) is

6cos60^(@) -sin30^(@)+sin^(2)45^@+cos^(2)45^@

The value of (sin43^(@))/(cos47^(@))+(cos19^(@))/(sin71^(@))-8cos^(2)60^(@) is

sin47^(@)+cos77^(@)=cos17^(@)

Evaluate the ((3 cos 43^(@))/(sin 47^(@)))^(2) - (cos 37^(@) "cosec" 53^(@))/(tan 5^(@) tan 25^(@) tan 45^(@) tan 65^(@) tan 85^(@))

The value of (sin43^(@) Cos47^(@) + cos43^(@) sin47^(@)) is …….. .

Q.Determine x if (x sin^(2)30^(@)cos^(2)60^(@))/(4cos^(2)45^(@))=(3sin^(2)45^(@)+2cos^(2)30^(@))/(sin^(2)90^(@)-4cos^(2)45^(@))
