Examples: Here are some examples of trigonometry and arithmetic with complex numbers: Evaluate sin (2 + i 3) Keys: Display: Description: 32 {GO Result is 9.1545 - i 4.1689. Evaluate the expression z 1 ÷ (z2 + z3), where z1 = 23 + i 13, z2 = -2 + i z3 = 4 - i 3 Since the stack can retain only two complex numbers at a time, perform the calculation as Keys: z1 × [1 ÷ (z2 + z3)] Display: Description: 1 2 ^ 3 ^ 4 { G {G 13 23 {Gz Add z2 + z3; displays real part. 1 ÷ (z2 + z3). z1 ÷ (z2 + z3). Result is 2.5 + i 9. Evaluate (4 - i 2/5) (3 - i 2/3). Do not use complex operations when calculating just one part of a complex number. Keys: Display: Description: 25^ 4 Enters imaginary part of first complex number as a fraction. Enters real part of first complex number. 9-4 Operations with Complex Numbers
