WebSolution: − 81 4 = 81 4 ⋅ − 1 4 = 81 1 4 ⋅ ( − 1) 1 4 Using 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 − 2.12132034 i WebThe value of tan 81 degrees can be calculated by constructing an angle of 81° with the x-axis, and then finding the coordinates of the corresponding point (0.1564, 0.9877) on the unit circle. The value of tan 81° is equal to the y-coordinate(0.9877) divided by the x … forest lagoon island
What is the value of √81=? - Quora
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: WebEvaluate 81^ (1/4) 811 4 81 1 4. Simplify the expression.
