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 + bi) = (c + bi) =






2. Root negative - has letter i






3. 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.






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

5. x / r






6. Where the curvature of the graph changes






7. 2a






8. 1






9. All the powers of i can be written as






10. What about dividing one complex number by another? Is the result another complex number? Let's ask the question in another way. If you are given four real numbers a -b -c and d - can you find two other real numbers x and y so that






11. Written as fractions - terminating + repeating decimals






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






13. A subset within a field.






14. The complex number z representing a+bi.






15. Like pi






16. 4th. Rule of Complex Arithmetic






17. The field of numbers of the form - where and are real numbers and i is the imaginary unit equal to the square root of - . When a single letter is used to denote a complex number - it is sometimes called an 'affix.'






18. To simplify the square root of a negative number






19. When two complex numbers are divided.






20. Not on the numberline

23. z1z2* / |z2|²






24. E^(ln r) e^(i?) e^(2pin)






25. I^2 =






26. 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.






27. The reals are just the






28. A complex number may be taken to the power of another complex number.






29. Complex Plane = i - Use the distance formula to determine the point's distance from zero - or - the absolute value.






30. A complex number and its conjugate






31. ½(e^(iz) + e^(-iz))






32. Solutions to zn = 1 - |z| = 1 - z = e^(i?) - e^(in?) = 1






33. R^2 = x






34. 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






35. The modulus of the complex number z= a + ib now can be interpreted as






36. Numbers on a numberline






37. I = imaginary unit - i² = -1 or i = v-1






38. 1






39. E ^ (z2 ln z1)






40. 1st. Rule of Complex Arithmetic






41. A² + b² - real and non negative






42. 2nd. Rule of Complex Arithmetic

43. Rotates anticlockwise by p/2






44. (2-3i)-(4+6i)you would distribute the negitive and combine your like terms and your answer is -2-9i






45. V(zz*) = v(a² + b²)






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






47. Divide moduli and subtract arguments






48. A+bi






49. A number that can be expressed as a fraction p/q where q is not equal to 0.






50. R?¹(cos? - isin?)
