HP 35s Working with complex numbers – part 2
Answer: 25 + 31i. Figure 3 shows the display in algebraic mode.
Example 2: Extract the X and Y coordinates of the complex number 5Θ30. Use degrees mode.
Solution: Changing the display mode to
However, to extract the X and Y values, it is necessary to leave the display in polar form using the
º^ function to extract the magnitude and the ¹= function to extract the angle. Once
extracted, the X and Y coordinates can be computed for further use as follows:
X = r COS Θ
Y = r SIN Θ
