The tan() function in p5.js is used to calculate the tangent value of an angle in radians taken as the input parameter of the function.
Syntax:
tan(angle)
Parameters: This function accepts a single parameter angle which is an angle in radian whose tangent value is to be calculated.
Return Value: It returns the tangent value of an angle in radian taken as the input parameter.
Below program illustrates the tan() function in p5.js:
Example: This example uses tan() function to get tangent value of an angle in radian.
function setup() {
createCanvas(550, 130);
}
function draw() {
background(220);
let a = 0;
let b = 8.9;
let c = 47;
let d = 5;
let v = tan(a);
let w = tan(b);
let x = tan(c);
let y = tan(d);
textSize(16);
fill(color( 'red' ));
text( "Tangent value of angle 0 (in radian) is : " + v, 50, 30);
text( "Tangent value of angle 8.9 (in radian) is : " + w, 50, 50);
text( "Tangent value of angle 47 (in radian) is : " + x, 50, 70);
text( "Tangent value of angle 5 (in radian) is : " + y, 50, 90);
}

Output:
Note: In the above code, the input angle should be in radian. For converting the degree into radian use the following formula:
Angles_in_radian = (π/180)*angles_in_degree
