WebbMathematical Induction Problems Practice the mathematical induction questions given … Use mathematical induction to prove De Moivre's theorem [ R (cos t + i sin t) ] n = R n (cos nt + i sin nt) for n a positive integer. Solution to Problem 7: STEP 1: For n = 1 [ R (cos t + i sin t) ] 1 = R 1 (cos 1*t + i sin 1*t) It can easily be seen that the two sides are equal. Visa mer Solution to Problem 3: Statement P (n) is defined by 13 + 23 + 33 + ... + n3 = n2 (n + 1) 2 / 4 STEP 1: We first show that p (1) is true. Left Side = 13 = 1 Right Side = 12 (1 + 1) 2 / 4 = 1 hence p (1) … Visa mer Statement P (n) is defined by n! > 2n STEP 1: We first show that p (4) is true. Let n = 4 and calculate 4 ! and 2n and compare them 4! = 24 24 = 16 … Visa mer Statement P (n) is defined by n3 + 2 n is divisible by 3 STEP 1: We first show that p (1) is true. Let n = 1 and calculate n3 + 2n 13 + 2(1) = 3 3 is … Visa mer Statement P (n) is defined by 3n > n2 STEP 1: We first show that p (1) is true. Let n = 1 and calculate 31 and 12 and compare them 31 = 3 12 = 1 3 is greater than 1 and hence p (1) is true. Let us also show that P(2) is true. 32 = 9 22 … Visa mer

WebbProof by Induction Step 1: Prove the base case This is the part where you prove that P (k) P (k) is true if k k is the starting value of your statement. The base case is usually showing that our statement is true when n=k n = k. Step 2: The inductive step This is where you assume that P (x) P (x) is true for some positive integer x x.
