First Quadrant:All the angles between 0⁰ and 90⁰ lie in the first quadrant. The value of all the functions (Sin, Tan, Cos) in this quadrant are positive. Shown as A (represents All) in the second diagram given below. Second Quadrant:All the angles between 90⁰ and 180⁰ lie...
The value of cos 120° is -1/2 or -0.5 as it lies in the 2nd quadrant where cosine is negative. The formula of cosine is, cos x = (adjacent side) / (hypotenuse). Here, the adjacent side is adjacent to angle x, and the hypotenuse is the triangle’s longest side. Students can ...
