Please help me i need full answer.

see explanation

Step-by-step explanation:

Using the sum/ difference → product formula

cos x - cos y = - 2sin( )sin ( )

sin x - sin y = 2cos ( )sin ( )

Given

(cosA - cosB)² + (sinA - sinB )²

= [ - 2sin()sin( ) ]² + [ 2cos( )sin( ) ]²

= 4sin² ( )sin² ( ) + 4cos² ( )sin² ( )

= 4sin² ( )[ sin² ( ) + cos² ( ) ← sin²x + cos²x = 1

= 4sin² ( ) × 1

= 4sin² ( ) = right side ⇒ proven

entering that problem on the tube might get you an answer

answer

false

explanation
