CLEP General Mathematics: Complex Numbers

Subjects : clep, math
Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. A complex number may be taken to the power of another complex number.






2. (a + bi) = (c + bi) =






3. Ln(r e^(i?)) = ln r + i(? + 2pn) - for all integers n






4. The product of an imaginary number and its conjugate is






5. Like pi






6. (2-3i)-(4+6i)you would distribute the negitive and combine your like terms and your answer is -2-9i






7. Real and imaginary numbers






8. I






9. 1






10. 3rd. Rule of Complex Arithmetic






11. 2ib






12. xpressions such as ``the complex number z'' - and ``the point z'' are now






13. 5th. Rule of Complex Arithmetic






14. I^26/4= i^24 x i^2 =-1 so u divide the number by 4 and whatevers left over is the number that its equal to.






15. Numbers on a numberline






16. Where the curvature of the graph changes






17. 3






18. Imaginary number

19. V(zz*) = v(a² + b²)






20. x / r






21. ½(e^(iz) + e^(-iz))






22. (2+i)(2i-3) you would use the foil methom which is first outter inner last. (2x2i)(2x-3)(ix2i^2)(ix(-3) =i-8






23. I^2 =






24. Have radical






25. A subset within a field.






26. x + iy = r(cos? + isin?) = re^(i?)






27. (a + bi)(c + bi) =






28. Notice that rules 4 and 5 state that we complex numbers together - we can divide by c + di if c and d are not both zero. But there is a much easier way to do division.

29. We can also think of the point z= a+ ib as






30. A number that cannot be expressed as a fraction for any integer.






31. 1






32. To simplify a complex fraction






33. zn = (cos? + isin?)n = cosn? + isinn? - For all integers n

34. The field of all rational and irrational numbers.






35. Has the opposite sign of a complex number; the conjugate of a + bi is a - bi






36. To simplify the square root of a negative number






37. Formula: z1 · z2 = (a + bi)(c + di) = ac +adi +cbi +bdi² = (ac - bd) + (ad +cb)i - when you multiply a complex number by its conjugate - you get a real number.






38. (2i+3)/(9-i)for the denominator you multiply by the conjugate and what u do to the bottom u have to do to the top then you distribute the bottom then the top then add like terms then you simplify. 21i+25/17






39. Cos n? + i sin n? (for all n integers)






40. Not on the numberline






41. Written as fractions - terminating + repeating decimals






42. 2nd. Rule of Complex Arithmetic

43. When two complex numbers are added together.






44. When two complex numbers are divided.






45. We consider the a real number x to be the complex number x+ 0i and in this way we can think of the real numbers as a subset of






46. The complex number z representing a+bi.






47. A + bi






48. V(x² + y²) = |z|






49. 1






50. A complex number and its conjugate
