Concept used:
Expand the equation by using the formula
Calculations:
Let
Left hand side of the equations
Thus the expand form is
b.
To separate: Real part and imaginary part Left hand side of the equation
The real part is
Given information:
The given equation
Concept used:
Expand the equation by using the formula
Calculations:
Let
Left hand side of the equations
Thus the expand form is
Now separate the term as real part and imaginary part by equating the like terms .
Thus real part is
