         k  ,x=Π/2

is continuos at x= Π/2 then k is equal to ?

Answers : (1)


f(x) is continuous at x=pi/2   so left hand limit is equal to right hand limit is equal to value of function at given pt

   so the left hand limiting value is found by applying L-Hopital''s rule three times.....the limit value is equal to k

it is functional value

Proved that acosA+bcosB+ccosC=2asinBsinC please help sir
Use properties of triangles. let area of triangle be Ar. Then bcsinA= casinB = absinC = 2Ar thus write all sin terms in terms of Ar. and also use a/sinA = b/sinB = c/sinC = k.
