Question

if cosx1+cosx2+cosx3+cosx4+cosx5= 5 then sinx1+sinx2+sinx3+sinx4+sinx5=?

Answer 1

Hey Mate

your answer is here

we know that maximum value of Cosx is 1

so,

given condition is possible if and only if

all Cosx term = 1

so,
all angle should be multiple of 2pi

and hence Sinx = 0 for all angle

so, your answer is zero.

Thanks
