p5.js | tan() function

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.



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() { 
    // Create Canvas of given size 
    createCanvas(550, 130); 
function draw() { 
    // Set the background color 
    // Initialize the parameter with
    // angles in radian only
    let a = 0; 
    let b = 8.9; 
    let c = 47;
    let d = 5;
    // Call to tan() function 
    let v = tan(a);
    let w = tan(b);
    let x = tan(c);
    let y = tan(d);
    // Set the size of text 
    // Set the text color 
    // Getting tangent value 
    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);     



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
