| − | == Trigonometric Cosine function ==
| |
| − | Now as in the figure of "Trigonometric Circle" as the angle theta increases and the transition line '''goes beyond 1st quadrant''', the value of some trigonometric functions change from positive to negative, like '''cosine function the ratio will be negative in the second and 3rd quadrant,''' the angle is '''always calculated from positive x-axis.''' So in-case cosine function inverse of the <math>a^2+b^2-c^2 /(2ab)</math> is a negative value then the angle which gives exactly same ratio in positive will be considered and subtracted from <math>\measuredangle</math>180 or <math>\pi </math> radians (while dealing with radians) to get exact angle from x-axis.

| − |
| |
| − | The generalized formula where the ratio would be (-x), then exact angle can be found like this:
| |
| − |
| |
| − | <math>\arccos (-x) =180 -\arccos (x) </math> (while using degrees)
| |
| − |
| |
| − | <math>\arccos (-x) =\pi-\arccos (x) </math> (while using radians)
