So, the answer is : Cot (45/2) =Cos (45)/ (1-Sin (45)) Cos 45 = 1/√2 1-Sin 45 = 1–1/√2 1-Sin 45 = (√2–1)/√2 Cos 45 / (1-Sin 45 ) = (1/√2)/ ( (√2–1)/√2) After solving this we get :

WebThe cotangent law says, (cot A/2) / (s - a) = (cot B/2) / (s - b) = (cot C/2) / (s - c). Here, 's' is the semi-perimeter of the triangle. i.e., s = (a + b + c)/2. Sign of Cotangent. The cotangent ratio (of course, both tan and cot) is … WebThe functions sine, cosine and tangent of an angle are sometimes referred to as the primary or basic trigonometric functions. The remaining trigonometric functions secant (sec), cosecant (csc), and cotangent (cot) … furniture shop fortitude valley
