Given:
bisects ∠RST.
To find:
The .
Solution:
Since, bisects ∠RST, therefore
...(1)
Now,
[Using (1)]
Therefore, the value of is .
Answer:
Step-by-step explanation:
If a complex number is z=a+ib, then the trigonometric form of complex number is
where, and , is called the argument of z, .
The given complex number is -5i.
It can be rewritten as
Here, a=0 and b=-5. lies in 4th quadrant.
So, the trigonometric form is
