II | x < 0, y > 0 | π – |

III | x < 0, y < 0 | -π + |

IV | x > 0, y < 0 | |

**What is the value of 1 iota?**

√-1

What is Iota and Its Value? Iota is an imaginary unit number that is denoted by i and the value of iota is √-1 i.e., i = √−1.

**What is the absolute value of 2 i?**

Explanation: Absolute value of a complex number a+ib is written as |a+ib| and its value as √a2+b2 . Hence, absolute value of −2−i is √(−2)2+(−1)2=√4+1=√5 .

### What is the absolute value of 4 i?

Expert Answer The absolute value of the number 4i is 4.

**What is the polar form of 1 i?**

∴−1+i=2 (cos43π+isin43π)

**What is the principal argument of (- 1 i where i?**

Supposing you mean (-i -1)/i. That’s equal to -1 -(-i) = -1+i, which lies in the 2nd quadrant at an angle bisecting the negative x-axis and the positive y-axis, so its argument is 3pi/4.

## What is the absolute value of 3?

3

For example, the absolute value of 3 is 3, and the absolute value of −3 is also 3. The absolute value of a number may be thought of as its distance from zero.

**What is the polar form of z1 i Complex?**

r = √2 and θ = π / 4. The polar form is √2 (cos π / 4 + i sin π / 4).

**What is the argument of the complex number (- i 1 )/ i?**

Hence: arg(−1−i)=−3π4.

### What is the value of i6?

Value of Powers of i

i3 | i2 * i | -i |
---|---|---|

i6 | i2 * i2* i2 | −1 |

i0 | i1-1 = i1.i-1 = i1/i = i/i =1 | 1 |

i−1 | 1/-i = -i/(-i)2 = -i/1 | −i |

i−2 | 1/i2 | −1 |

**What is 3i imaginary number?**

Since −3i is an imaginary number, it is the imaginary part (bi) of the complex number a + bi. This imaginary number has no real parts, so the value of a is 0. Answer. 0 – 3i.

**What’s the absolute value of 5?**

5

The absolute value of 5 is 5. The distance from 5 to 0 is 5 units.

## In which quadrant of the complex plane does the number − 1 − i lie?

= (-1+3i)/2, lies in second quadrant. Hence option (3) is the answer.

**What is the modulus of 1 i )/( 1 i?**

**What is argument of iota?**

Argument of z = a+ib is equal to tan-1(b/a) Hence, argument of -1-i = tan-1(-1/-1) = pi/4.
