How to find the tangent of the angle

Suppose we are given a Cartesian coordinate system, and it, in any place, come to an end. Draw a straight line through the origin and the point.

We find the tangent of the angle between the straight line and the axis of abscissa.

You will need

  • Knowledge of formulas in trigonometry and basic knowledge of geometry.

The tangent of the angle between the straight line and the axis of abscissais equal to the ratio of the Y coordinate point to the coordinate point X this. Another way to find the tangent of an angle is possible by means of sines and cosines. If you know the value of the cosine and sine of the angle is the angle that the tangent is equal to the ratio value of the sine to the cosine.
