$$\cos 120\degree=\cos\frac{2\pi}{3}=\frac{(-1)\cdot\text{Cateto adyacente}}{\text{Hipotenusa}}=-\frac{1}{2}$$ Es decir, el coseno de 120 grados o 2π/3 radianes es igual a menos uno partido por dos. Por simetría puede deducirse que el coseno de 120° es exactamente igual al coseno de 240°. Puedes ver esta igualdad representada en el

Memorize the unit circle For each point on the circle, the x-coordinate is the cosine value of that angle, and y-coordinate is sine. Memorization is easier than it looks in the picture, because the circle is symmetrical across both the x and y axi Cos^2A+cos^2(A+120)+cos^2(A-120)=3/2 prove its urgent. 2 See answers anurag36 anurag36 I hope it will help u thanku very much.it really helped your welcome lovingheart lovingheart The proof is as follows.

Find the Exact Value cos(120) Apply the reference angle by finding the angle with equivalent trig values in the first quadrant. Make the expression negative because cosine is negative in the second quadrant. The exact value of is . The result can be shown in multiple forms. Exact Form: There is a certain degree of ambiguity which I can fairly associate with this question since any number, with regards to trigonometric functions, without a unit adjacent to it, can be considered immediately as an angle in radians.
