Division is the opposite of multiplication, so (7/i) equals 90 degrees, or 270 degrees.
What is 5i equal to?
The imaginary number i is equal to the square root of 1. In other words, i2 is equal to 1. The square root of a negative number is not a real number and it is not a variable. For example, the square root of 25 is written as 5i because 5i multiplied by 5i equals 25 multiplied by 1 or 25. 3
What is 2i the same?
The absolute value of the complex number 2i is 2.
What is the complex conjugate of 7i?
The complex conjugate We replace all i with −i: 7i becomes −7i, 2+ 3i becomes 2− 3i, and in general a+bi becomes a−bi.
What is 8i?
+8. I believe it means the imaginary number. However, it could be any number like x or n or y. The imaginary number is what you get when you take the square root of negative numbers because no squared real number gives a negative result, people chose a number and the name of the imaginary number is stuck on it.
What does 3i mean in math?
Therefore 3i means nothing more than the square root of 9.
What is the conjugate of 3 I?
The given complex number is 3 + i. Here a=3 and b=1. Hence the conjugate of the complex number 3 +i is 3i .
What is the complex conjugate of Z?
You can easily verify that a complex number z = x + yi times its conjugate x – yi squares its absolute value | is z | 2 . So 1/ z is the conjugate of z divided by the square of its absolute value | z | 2 .
