Cos 90-theta

In Mathematics, there are a total of six different types of In a Right-Angled Triangle • Sine (θ) = Opposite/Hypotenuse • Cos (θ) = Adjacent/Hypotenuse • Tan (θ) = Opposite/Adjacent • Cot (θ) = Adjacent/Opposite • Cosec (θ) = Hypotenuse/Opposite • Sec (θ) = Hypotenuse/Adjacent In this topic, we will discuss what is cos theta and the values of different angles. Cos Angle Formula In a right-angled triangle. The Cos theta or cos θ is the ratio of the adjacent side to the hypotenuse. (Image will be uploaded soon) In the given right angle triangle A is an adjacent side, O is perpendicular and H represents the hypotenuse. Cos θ = Adjacent/Hypotenuse Here θ represents the angle of a triangle. The angles by which trigonometric functions can be represented are called θ 0° 30° 45° 60° 90° sin θ 0 1/2 1/√2 √3/2 1 cos θ 1 √3/2 1/√2 1/2 0 tan θ 0 1/√3 1 √3 Undefined cosec θ Undefined 2 √2 2/√3 1 sec θ 1 2/√3 √2 2 Undefined cot θ Undefined √3 1 1/√3 0 Note: 1 cos theta = 1. Cos θ; Eg: 1 cos 30° = 1. Cos 30° = 1 x √3/2 = √3/2 And cos θ = \[\frac\] Also, sin (90 - θ) = cos θ and Cos (90 - θ) = sin θ. Also remember sin 45 = cos 45 = 1/√2. The Definition of Cos Theta 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 ...
