#Ti nspire complex numbers polar form how to

Why is it giving me a different output? What is going wrong here? Also, it is saying that e^(i*100)/e^(i*50)= e^(i*-15.211). Also, if I put the calculator in polar mode and input e^(i*45) the output is: 1e^(58.31).

The abbreviated polar form of a complex number is z rcis, where r (x 2 + y 2) and tan-1 (y/x). The polar form of a complex number z x + iy with coordinates (x, y) is given as z r cos + i r sin r (cos + i sin). My understanding of complex numbers leads me to believe that the output should have been: cos(45)+sin(45)*i =. Equation of Polar Form of Complex Numbers. However, if I input (while the calculator is in degrees mode, and it is set up to output complex quantities in rectangular form) e^(i*45) and press enter the output is.

Then practice graphing complex numbers in the polar coordinate plane. Explore the concept of, and use the Ti-Nspire to, convert complex numbers into polar form. Correct me if I'm wrong, but it my understanding of switching back and forth between rectangular and polar forms of complex numbers is the following : A*e^(i*x) => A cos(x) + i sin(x) This Complex Numbers: Plotting and Polar Form Lesson Plan is suitable for 9th - 12th Grade. This is especially apparent if I try to enter complex numbers into my calculator in their polar form. In the same way that graphs of relationships in cartesian form can be sketched, relationships expressed in polar form can also be.

I have been finding that some of the calculations that my calculator has been making don't really make sense. This requires a bit of algebra with complex numbers. The place where I always make a mistake is in clicking (just one time) on those little boxes in the InfixNotation template.So, I'm trying to do some calculations for my Electrical engineering homework. To add, subtract, multiply, and divide complex numbers: Enter the numbers in either format. However, if your calculator is set to return degrees, the answer will display degrees. By multiplying the phase angle in degrees by (as in the example above), the angle is converted from degrees to radians. If it doesn't work, or if you get an error when press Shift-Enter to evaluate the InfixNotation command, delete that InfixNotation command and try it again with a fresh template from the Notation Palette. NOTE: When entering complex numbers in polar form on the TI-84 Plus, you must enter the angle in radians. If it works, save your notebook with the InfixNotation template already filled in.

Here is a bit of code that may give you some ideas about how to display numeric complex values in phasor notation.
