Cot b - cot a
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.

WebB.Tech from BANSAL INSTITUTE OF ENGINEERING &TECHNOLOGY (Graduated 2024) 3 y We know the formula of Cot (A/2) = Cos (A)/ (1- (Sin (A)); Where A is the theta. 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 :
