Question

let a is equal to 2 sin theta by 1 + sin theta + cos theta and b is equal to C by 1 + sin theta and a is equal to b then find the value of c please be fast its an emergency ​

Answer 1

Step-by-step explanation:

Correct option is

B

a2+b2≤4

sinθ1−sinθ2=a⟶(1)   

cosθ1−cosθ2=b⟶(2) 

Squaring and adding (1) and (2)

a2+b2=2(1−cos(θ1−θ2))

and, −1<cos(θ1−θ2)<1

Therefore,

0≤a2+b2≤4

 

Hence, option 'C' is correct.
