Name

tan()

Description

Calculates the ratio of the sine and cosine of an angle. This function expects the values of the angle parameter to be provided in radians (values from 0 to PI*2). Values are returned in the range infinity to ‑infinity.

Examples

  • size(400, 400);
    
    float a = 0.0;
    float inc = TWO_PI/50.0;
    
    for (int i = 0; i <= 400; i = i+8) {
      line(i, 200, i, 200+tan(a)*8.0);
      a = a + inc;
    }
