WebThe value of cot pi/4 can be calculated by constructing an angle of π/4 radians with the x-axis, and then finding the coordinates of the corresponding point (0.7071, 0.7071) on the unit circle. The value of cot pi/4 is equal to the x-coordinate (0.7071) divided by the y-coordinate (0.7071). ∴ cot pi/4 = 1 WebTo solve a trigonometric simplify the equation using trigonometric identities. Then, write the equation in a standard form, and isolate the variable using algebraic manipulation to …

WebSep 23, 2024 · 1 Answer Monzur R. Sep 23, 2024 cos( π 4 + π 3) = √2 −√6 4 Explanation: In order to evaluate cos( π 4 + π 3) we need to use the compound angle formula for cos: cos(A+ B) ≡ cosAcosB − sinAsinB ∴ cos( π 4 + π 3) = cos( π 4)cos( π 3) −sin( π 4)sin( π 3) = 1 √2 ⋅ 1 2 − 1 √2 ⋅ √3 2 = 1 2√2 − √3 2√2 = 1 −√3 2√2 = √2 −√6 4 Answer link WebJun 9, 2024 · tan( π 4) = 1 csc( π 4) = √2 sec( π 4) = √2 cot( π 4) = 1 Explanation: π 4 radians is the same as 90 degrees. So, first draw a right triangle with an angle of π 4: This creates a 45-45-90 triangle, also … bridge tadworth
Solved Find the exact value of the trigonometric expression - Chegg
WebThe angles that they're picking are ones that can be made by adding angles that are easy to remember, namely pi/6, pi/4, pi/3, and pi/2 (30, 45, 60, and 90, respectively) and their multiples. You can use angle addition to quickly find the trig values of, say, 75 degrees, since it's easy to see that 45+30=75. WebTrigonometry.
