# Can't transform from polar to rectangular

which is diffrent from the (e) of the exponantial
thanks

I have the same problem but in Casio Algebra FX2.0 Plus. I can't find the (e) letter which is needed to complex transformation. When i transform from rectangular form to the polar form, there is no problem, but if i want to change the polar form to rectangular form, i have to type (e) which isn't the same as the e in function e^x. And i ca't find other "e" in this calculator. Help please.

Hello,
The e is the same, it is the exponential. According to Euler's relation
e^(i theta) = cos(theta) + i sin(theta), where i is the imaginary unit.
When represented on the complex plane (x,iy) the point (cos(theta), sin(theta)) is at the extremity of a vector of length 1 and making an angle theta with the real axis.

In (plane) polar coordinates, a point is defined by the radius r, and the angle, theta, it makes with the x axis, measured in the trigonometric (counterclockwise) direction. It is structurally equaivalent to representing it in the complex plane as r*e^(i*theta). Since r is the measure ot is radius, and the theta is it argument (angle). The complex notation is used for its convenience when adding vectors (as is AC circuits)
That is the theory.
I am inserting a clipping from the book to show you how to convert between polar and rectangular coordinates.

OOPS. Typos
Since r is the measure of its radius instead of Since r is the measure ot is radius.

### How do I add or subtract numbers in polar form or rectengular form

If one or both numbers are in polar form, convert it/them to rectangular. Once both numbers are in rectangular form, simply add the two components separately: Add the two x components together, and add the two y components together.

If you're asking how to do this on a particular calculator, please specify the make and model.

### Polar to rectangular conversion working incorrectly

At first, Rect and Polar are a display-format instructions, not a conversion functions. Polar instruction displays complex value in rectangular form a + bi. The complex value can have any complex form. However, an r*exp(i*theta) causes an eror in Degree angle mode according to the TI avowal. See captured images below
