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 Value of Cos 120 is -½. It has many other applications too. In some cases, it is used indirectly. For example, in creating computer music as sound travels Answer: The value of cos 120 degrees is -1/2. Let us find the value of cos 120°with the help of the trigonometry formulas. Explanation:. The value of cos 120 degrees can be calculated by constructing an angle of 120° with the x-axis, and then finding the coordinates of the corresponding point (- Dec 25, 2016 You can use a reduction formula. See explanation. cos120=cos(180-60)=-cos60=-1/2. Oct 30, 2015 cos-120^@=-1/2=-0,5 cos(-120^@)=cos120^@ =cos(180^@-60^@) =-cos60^@ =-1/2. Note: Above I have used the 180^@ rule. In this video, we learn to find the value of cos120. Here I have applied cos(90 + x) = -sin(x) identity to find the value of cos(120).
