May 29, 2023 · sin(15) = sin(45-30) by using sin(A-B) formula. sin(45-30) = sin45cos30 - sin30cos45 = (1/√2)(√3/2) - (1/2)(1/√2) = (√3/2√2) - (1/2√2) = (√3 - 1)/2√2. cot 15= cos15/sin15 = (√3 + 1)/(√3 - 1) simplifying this gives the exact value of cot 15. if there is any calculation mistake plz ignore it, you got the idea right on how to ...

Aug 2, 2021 · The cot of 15 degrees is 2+√3, the same as cot of 15 degrees in radians. To obtain 15 degrees in radian multiply 15° by / 180° = 1/12 . Cot 15degrees = cot (1/12 × . The value of cot 15° is . Multiply both numerator and denominator by . Therefore the value of cot 15° is
