How To Add Phasors On Ti 84

Your TI-84 Plus calculator has a CMPLX menu of functions designed to reach just nearly any task you need to when working with complex numbers.

The functions most oft used with complex numbers are all located in ane convenient location on your calculator. To access the CMPLX menu, printing

Finding the cohabit of a complex number

Finding the conjugate of a complex number is so like shooting fish in a barrel that yous probably don't need a reckoner for the job. In case y'all do, press [1] on the CMPLX carte to utilise the Conj office. Enter the expression y'all want to detect the conjugate of and press [ENTER]. See the second screen.

Finding the real and imaginary parts of a complex number

This is another function that seems to do the obvious, indicating they are mainly used in programming. In the CMPLX menu, press [ii] to insert the Real function or press [3] to insert the Imag function. Enter a complex number in the argument and press [ENTER] to run across your predictable results shown in the 3rd screen. These tools only identify the real or imaginary office of a complex number.

Earlier proceeding, press [Way] and make sure your calculator is in RADIAN mode. Generally speaking, this is the recommended mode for all complex number calculations.

Finding the polar angle of a complex number

The Angle function uses the formula tan^– ¹( b / a ) to calculate the polar angle of a complex number (where a is the real part and b is the imaginary part). In the CMPLX menu, press [iv] to insert the Angle role, type a circuitous number in the argument, and then press [ENTER]. See the starting time screen.

Finding the magnitude (modulus) of a circuitous number

Inbound a circuitous number in the absolute value template finds the magnitude (modulus) of the circuitous number. Algebraically your calculator uses the formula

for the adding. In the CMPLX bill of fare, printing [5] to admission the abs function, type a circuitous number, and and then press [ENTER]. Run across the second screen.

Press [ALPHA][WINDOW] to access the abs role in the shortcut card.

Displaying a circuitous result in polar or rectangular form

The last two choices in the CMPLX menu work only when inserted after typing a complex number. Use Rect to display a complex number in rectangular form. To brandish a circuitous number in polar form, select Polar from the CMPLX menu. See the get-go two lines of the concluding screen.

Relieve time converting complex numbers to polar form past irresolute the mode of your computer to
