WebApr 7, 2024 · The Cos Theta Formula is a Mathematical formula used to calculate the Cosine of an angle. It can be abbreviated as Cos (θ) and looks like this: Cos (θ) = adjacent/hypotenuse. In other words, it takes the length of the adjacent side (the side next to the angle) and divides it by the length of the hypotenuse (the longest side of a right … WebDec 2, 2016 · The two minimum values of angle, θ are 60° & 300°. Explanation: Given that, cosθ = 1 2. But, it is known that, cos60° = 1 2. Also, cos300° = 1 2. ∴ θ = 60° & θ = 300°. So, θ has lots of values for which their cosine function is 1 2. But, the two least values of θ are 60° & 300°. Answer link
