Question

cosX + cosY = 2 then sinX + sinY​

Answer 1

Answer:

sinx+siny=2

Step-by-step explanation:

Answer 2

answer is 0

we know that maximum value of cosx is 1

so for getting 2,

it should be cosx + cos y =2

1+1 =2

cos0 + cos0 =2

so ,sinx+ siny = sin0+ sin0 =0

remember one thing, cos can have only the maximum value 1 (when theetta=nπ)
