Question

sin(a - 540°) =
find the value..​

Answer 1

Answer:

Step-by-step explanation:

Sin(a-540)

= -Sin(540-a)

= -Sin(360+180-a)

= -Sin(180-a)

= -Sina

FORMULAE

Sin(360+A) = SinA

Sin(-A) = -SinA

Sin(180-A) = SinA

Answer 2

Answer:

sin(a)cos(540)-cos(a)sin(540)

sin(a)×-(1)-Cos(a)×0

-sin(a)×cos(a)×0=-sun(a)

-sin(a)

-sin(a)
