Small details of mathematical problems are adopted in time. What I want to ask is: 1 How did this angle come from? Is there a corresponding formula? Help me analyze it in detail.

The angle between a straight line and the positive direction of the X axis (called the inclination angle of the straight line) or the tangent of the angle (called the slope of the straight line) is often used to indicate the inclination of the straight line on the plane (for the X axis).

The slope of the straight line is 1/ root number 3, that is, root number 3/3, so tanα= root number 3/3 and α=π/3.

Recently, as long as I insist on doing math problems for more than an hour, I have a headache and feel that my energy can't keep up with the college entrance examination. What should I do?
