Cot 11pi/12
WebYou can put this solution on YOUR website! what is the exact value of sin (11pi/12) There are 6 different ways we can go about this since can be written in as the sum or difference of special angles in these 6 ways: = = = = = = I'll pick one arbitrarily, say = = We use the formula: = = = = = Edwin WebAug 27, 2015 · cost = cos( 11π 12) = ± √2 + √3 2. Since the arc ( (11pi)/12) is located in Quadrant II, only the negative answer is accepted. cos( 11π 12) = − √2 + √3 2 Check by calculator. Arc( 11π 12) = 165 deg-> cos( 11π 12) = cos165 = −0.97. −( √2 + √3 2) = −0.97. OK Answer link

WebThe value of cot 5pi/6 can be calculated by constructing an angle of 5π/6 radians with the x-axis, and then finding the coordinates of the corresponding point (-0.866, 0.5) on the unit circle. The value of cot 5pi/6 is equal to the x-coordinate (-0.866) divided by the y-coordinate (0.5). ∴ cot 5pi/6 = -1.7321. cerveza croata ozujskoWebDetermine angle type: 301 > 90°, so it is obtuse. sin (301) = -0.85716730379385. cerveza camaro mojitoWebJan 21, 2024 · If `cot^3 alpha+ cot^2 alpha + cot alpha=1` then which of the following is/are correct asked Jan 22, 2024 in Trigonometry by MukundJain ( 94.1k points) class-12 cerveza gran torobayoWebFind the value of cot(− 415π) Medium Solution Verified by Toppr It is known that the values of cotx repeat after an interval of π or 180 ∘. ∴cot(− 415π)=cot(−4π+ 4π) =cot 4π =1 Video Explanation Solve any question of Trigonometric Functions with:- Patterns of problems > Was this answer helpful? 0 0 Similar questions Prove the following: cerveza eku 28 graduaciónWebVideo Transcript.
