Question

14) Find the modulus and argument of each
complex number and express it in the polar
form
1) -3i​

Answer 1

Step-by-step explanation:

1. Mod of z is equal to........ Square root of sum of squares of constant term and the coefficient of "I"
2. Argument of z implies the angle formed by the Co_ordinates of the point I. E if we have a z=(x+iy)...... Therefore... Z can be represented in form of coordinates as (x, y). Now to calculate argument there are certain rules...... And formulaes
3. For polarise form of z there is a formula.... I. E
4. $z = |z| \times ( \cos( \alpha ) + i \sin( \alpha ) )$
5. In above formula the alpha is calculated via argument of z
