WebJul 8, 2024 · Time Complexity: O(n 2 sqrtx) where x is the max value of the third number. Auxiliary Space: O(1) Method-2: Find all the perfect squares upto n 2 and save it to an ArrayList.; Now for every a from 1 to n, do the following: . Choose c 2 from the list of perfect squares calculated earlier.; Then b 2 can be calculated as b 2 = c 2 – a 2.; Now check if a … WebWe can interpret the cotangent of a negative angle as cot(− θ) = cos ( − θ) sin ( − θ) = cosθ − sinθ = − cot θ. Cotangent is therefore an odd function, which means that cot(− θ) = − cot(θ) for all θ in the domain of the cotangent function. WebStep 8.3.2.2. Cancel the common factor. Step 8.3.2.3.
