Solve (sin40^(@))/(cos50^(@))+(csc40^(@))/(sec50^(@))

Find the value of (sin 50^(@))/(cos40^(@))+("cosec"40^(@))/(sec 50^(@))-4cos 50^(@) " cosec"40^(@).

Without using trigonometric tables,find the value of ((sin50^(@))/(cos40^(@)))+((cos ec40^(@))/(sec50^(@)))-4cos50^(@)cos ec40^(@)

Evaluate : (sin50^0)/(cos40^0)+(cos e c40^0)/(sec50^0)-4cos50^0cos e c40^0

Evaluate : (sin50^0)/(cos40^0)+(cos e c40^0)/(sec50^0)-4cos50^0cos e c40^0

Evaluate : sin50^(@)cos40^(@)+cos40^(@)+cos50^(@)sin40^(@)

Evaluate : sin50^(@)cos40^(@)+cos40^(@)+cos50^(@)sin40^(@)

Evaluate cos 40 ^(@) cosec 50 ^(@)+ sin 50 ^(@) sec 40 ^(@)

4cos^(3)40^(@)-3sin50^(@)=
