Value of Cos 120 degree can be calculated using other trigonometric angles 90 degrees and 180 degrees. These cosine values can be gained from the trigonometric table.
Cos 120 Degrees. The value of cos 120 degrees is -0.5.Cos 120 degrees in radians is written as cos (120° × π/180°), i.e., cos (2π/3) or cos (2.094395. . .). In this article, we will discuss the methods to find the value of cos 120 degrees with examples.
3 days ago · Vedantu’s article on cost 120° is mainly about the ways in which the value of course 120° can be calculated and it explains in-depth the various functions of trigonometry that is sin cos tan it explains in-depth what a hypotenuse, a perpendicular, and a base is.
May 4, 2023 · Value of cos 120 degrees is -0.5 or -1/2 & value of cos 120 in radians is \(\cos \left(\frac{2\pi }{3}\right)\) or cos (2.0943951). It’s a trigonometric ratio that symbolizes a function in the second quadrant. As the value of cosine is negative in the second quadrant so cos 120 will have a negative value.
Jan 24, 2023 · Cos 120°: Value. In order to find the value of cos 120°, students need to draw a right-angled triangle (refer to the image below) and can use either of the two formulas i.e, cos (180° – θ) = – cosθ or cos (90° + θ) = – sinθ.
