WebNov 2, 2016 · Explanation: Since 81 is much larger than 3, our answer will be a decimal, so let's think of this problem in the opposite sense: log3(81). 34 = 81, so log3(81) = 4. Using the law of exponents, we know that if am = n, then n1 m = a. So using this rule, we know that 811 4 = 3, so log81(3) = 1 4 Answer link WebUsing DeMoivre's Theorem we get the equation. = 81 1 4 ⋅ ( c o s ( ( 2 k + 1) π 4) + s i n ( ( 2 k + 1) π 4) i) Solving our equation for k=0 to k=n-1 (for k = 0, 1, 2 and 3); The roots of − 81 4 are: 2.12132034 + 2.12132034 i. − 2.12132034 + 2.12132034 i. − 2.12132034 − …

WebExample 1: Using the value of tan 81°, solve: (sec² (81°) - 1). Solution: We know, (sec² (81°) - 1) = (tan² (81°)) = 39.8635 ⇒ (sec² (81°) - 1) = 39.8635 Example 2: Find the value of tan 81° if cot 81° is 0.1583. Solution: Since, tan 81° = 1/cot 81° ⇒ tan 81° = 1/0.1583 = 6.3138 Example 3: Find the value of 5 tan (81°)/6 tan (99°). Solution:
