Question

find the modulus&argument of complex number 0+i1​

Answer 1

HEY MATE....!!!

The complex number is 0+i

Okay, so here we've got x = 0 and y = 1 as we do not take in account the i

Then, if we need to find the modulus, the formula is,

modulus (r) = √x^2+ y^2

Modulus (r) = √0^2 + 1^2

= √1 = 1

OKAY, so the modulus is 1

Now, to get the argument, the formula is....

Argument or tan theta = | y/x |

Argument = | 1/0 |

so Tan theta = infinity

AND INFINITY IS THE VALUE OF TAN THETA IN RADIANS IS PI/2

HENCE ARGUMENT = PI/2

HOPE IT HELPS.....
