Question

What we write to Sin( θ1- θ2)

Answer 1

sin(θ1 - θ2) =Im(ei(θ1-θ2)

=Im(eiθ1 eiθ2)

=Im((cos θ1 - isin θ1)(cos θ2 + isin θ2)

= cos θ1 sin θ2 - sin θ1 cos θ2

Answer 2

$\huge\star\mathfrak\red{{Answer:-}}$

sin(θ1 - θ2)

Step-by-step explanation:

sin(θ1 - θ2) =Im(ei(θ1-θ2)

=Im(eiθ1 eiθ2)

=Im((cos θ1 - isin θ1)(cos θ2 + isin θ2)

= cos θ1 sin θ2 - sin θ1 cos θ2
