If x+sin y=2010 and x+2010cos y=2009, 0<`yle(pi)/(2)` then the final value of `[[x+y]] /100` is (where [.] denotes greatest integer function)

If x+sin y=2010 and x+2010cosy=2009, 0ltyle(pi)/(2) .then the final value of ( [x+y] )/(100) is (where [.] denotes greatest integer function)

If x+sin y=2010 and x+2010cos y=2009 where 0 lt y leq (pi)/(2) then the final value of [ x+y ]/(100) is (where . [.] denotes greatest integer function)

Given x + sin y = 2009 and x + 2009 cos y = 2008, where y in[0,(pi)/(2)] , then [x+y] equals, where [.] represents the greatest integer function,

If sin x + sin y = a and cos x + cos y = b , what is sin x.sin y + cos x .cos y equal to ?

If sin x+sin y=a and cos x+cos y=b then thevalue of sin(x+y) is

If sin x + sin y + sin z = 0 and cos x + cos y + cos z = 0 then prove that cot (x+y)/2 = cot z and cos (x-y)/2 = pm 1/2

If (sinx + sin y ) = a and (cos x + cos y ) = b what is the value of sin x sin y + cos x cos y ?

If sin x + sin y = a, cos x + cos y = b, then what is the value of cos (x-y) ?
