WebMar 16, 2024 · First of all we can write 75 as 45 plus 30. Therefore, tan 75 = tan ( 45 + 30) And cot 75 = cot ( 45 + 30) Now, let us find the values of tan 75 and cot 75 separately. ⇒ … WebThe reciprocal of cotangent is the tangent: tan(x), ... For example, if in the illustration above b = 6 and a = 12, then cot(α) = 6 / 12 = 0.5. Applications of the cotangent function. The cotangent function is used in the ASA triangle rule (angle-side-angle). Other than that, it has not had many practical applications since calculators became ...
Web1/tan 15° Note: Since 15° lies in the 1st Quadrant, the final value of cot 15° will be positive. We can use trigonometric identities to represent cot 15° as, tan (90° - 15°) = tan 75°-tan (90° + 15°) = -tan 105°-cot (180° - 15°) = -cot 165° Cot 15 Degrees Using Unit Circle.
