`(2sin38^(@))/(cos52^(@))`

(sin52^(@)+cos38^(@))/(sin38^(@)+cos52^(@))

Find the value of sin 38^(@)-cos 52^(@) .

The value of (sin 38^(@) - cos 68^(@))/( cos 68^(@) + sin 38^(@) is

(sin18^(0))/(cos72^(0))+(sin22^(0))/(cos68^(@))-(cos38^(0)cos ec52^(0))/(tan18^(@)tan35^(@)tan60^(@)tan72^(@)tan55^(@))

Choose the correct answer in each of the following questions: (cos38^(@)"cosec"52^(@))/(tan18^(@)tan35^(@)tan60^(@)tan72^(@)tan55^(@))=?

The value of cos38^(@)cos52^(@)-sin38^(@)sin52^(@) is :

Show that : cos38^(@)cos52^(@)-sin38^(@)sin52^(@)=0

cos38^(@)cos52^(@)-sin38^(@)sin52^(@)=0
