Question: If x \< 0, then arg(x) is equal to...
If x < 0, then arg(x) is equal to
A
0
B
p/2
C
p
D
None of these
Answer
p
Explanation
Solution
Sol. x = x + i0
= – x (–1 + i0)
= – x(cosp + i sin p)
arg(z) = p
If x < 0, then arg(x) is equal to
0
p/2
p
None of these
p
Sol. x = x + i0
= – x (–1 + i0)
= – x(cosp + i sin p)
arg(z) = p
