Mock AIME Series Thomas Mildorf November 24‚ 2005 The following are five problem sets designed to be used for preparation for the American Invitation Math Exam. Part of my philosophy is that one should train by working problems that are more difficult than one is likely to encounter‚ so I have made these mock contests extremely difficult. The idea is that‚ once you become acclimated to them‚ the real AIMEs will seem easier‚ and you will approach them with justifiable confidence. Therefore‚ do not

z=2(cos(5π/6) + i sin(5π/6)) Apply De Moivre’s Theorem‚ z-10 = (√3 – i)-10 =2-10 (cos(10*5π/6) + i sin(10*5π/6)) = ...... And‚ I think you should be able to get the answer for (√3 – i)-10. 19. Sketch triangle and find other five ratios of θ. sin θ = 3/5 Step 1‚ we sketch a right triangle to specify the angle θ. Step 2‚ since we are given sin θ = 3/5‚ mark the opposite and hypotenuse as the graph below. Step 3‚ find out the missing length by using Pathagorean Theorem. 32 + adjacent2
