To convert the complex number 4 to polar form, you first need to represent it in the form a + bi, where a is the real part and b is the imaginary part. In this case, 4 can be written as 4 + 0i. Next, you calculate the magnitude of the complex number using the formula |z| = sqrt(a^2 + b^2), which in this case is |4| = sqrt(4^2 + 0^2) = 4. Finally, you find the argument of the complex number using the formula theta = arctan(b/a), which in this case is theta = arctan(0/4) = arctan(0) = 0. Therefore, the polar form of the complex number 4 is 4(cos(0) + i sin(0)), which simplifies to 4.

This doesn't need much conversion. Since the coefficient of i is zero the number is on the real axis. Since it has zero angle with the axis, the polar co-ordinates stare you in the face : r is 4, theta is 0.

How do you convert a complex number from polar form into rectangular form?

If the polar coordinates of a complex number are (r,a) where r is the distance from the origin and a the angle made with the x axis, then the cartesian coordinates of the point are: x = r*cos(a) and y = r*sin(a)


How do you convert the complex number minus i into polar form?

A COMPLEX NUMBER CAN BE CONVERTED INTO A POLAR FORM LET US TAKE COMPLEX NUMBER BE Z=a+ib a is the real number and b is the imaginary number THEN MOD OF Z IS SQUARE ROOT OF a2+b2 MOD OF Z CAN ALSO BE REPRESENTED BY r . THEN THE MOD AMPLITUDE FORM IS r(cos@Very interesting, but -i is not a complex no. it is a simple (imaginary) no. with no real part.


How do you convret polar form of complex number into algebraic form?

For a complex number in polar form with Magnitude, and Angle: (Magnitude)*(cos(angle) + i*sin(angle)) will give the form: a + bi


How do change a complex number to its standard form?

It isn't clear in what form you have the complex number. But you can change it from the form (absolute value, angle) to the form (real part + imaginary part) using the polar-rectangular conversion available on scientific calculators (and the other way round, with the rectangular-polar conversion). Note that a complex number in the form (real part + imaginary part) is most appropriate for addition and subtraction, while a complex number of the form (absolute value, angle) is most appropriate for multiplication or division, so depending on the operations, you may want to convert back and forth several times.


What is the exponential form for complex numbers?

Exponential form is similar to 'polar form'. Call the Magnitude A, and the angle θ .Then the number is represented as A*eiθ (θ in radians). To convert to rectangular form, use Euler's formula:eiθ = cos(θ) + i*sin(θ)So the complex number A*eiθ = A*cos(θ) + A*i*sin(θ)
