Answer 1

Hey Miss

Here's the answer

----------------------------------

Solution 4 :-

=> We can write

19π/3

= 6π + π/3

So

=> Sin ( 19π/3 )

=> Sin ( 6π + π/3 )

we know

Sin ( π + ∅ ) = sin ∅

=> sin ( π/3 )

=> √3/2

----------------------------

Solution 5 :-

Sin ( -1125° )

We know

Sin (-∅ ) = - sin (∅ )

=> - sin( 1125° )

=> - sin ( 3×360 + 45 )

We know

sin ( 360 + ∅ ) = sin ∅

=> - sin ( 45 )

=> - 1/√2

HOPE HELPED

PEACE :)

Answer 2

sin(19π/3 ) = sin( 6π + π/3) = sin( π/3 )

√3/2

now

sin ( -1125 )

- sin ( 3× 360 + 45 )

- Sin(45 )

-1/√2
