Calculate the cross and dot product of two vectors. Here is the web calculator to do it for you.

/* returns string representation of the cross product vector to the vector parameters parameters are the components of the two vectors (x1 is x component of first vector, x2 is x component of second vector, etc.) */ function crossProduct(x1, y1, z1, x2, y2, z2) { // components of cross product vectors var x = y1 * z2 - z1 * y2; var y = z1 * x2 - x1 * z2; var z = x1 * y2 - y1 * x2; return "(" + x + ", " + y + ", " + z + ")"; } /* returns dot product of vector parameters parameters are the components of the two vectors (x1 is x component of first vector, x2 is x component of second vector, etc.) */ function dotProduct3D(x1, y1, z1, x2, y2, z2) { // sum of the product of each of the components return x1 * x2 + y1 * y2 + z1 * z2; } /* returns dot product of vector parameters parameters are the components of the two vectors (x1 is x component of first vector, x2 is x component of second vector, etc.) */ function dotProduct2D(x1, y1, x2, y2) { // sum of the product of each of the components return x1 * x2 + y1 * y2; } // examples alert("Cross Product: " + crossProduct(1, 2, 3, 2, -1, 1)); // Cross Product: (5, 5, -5) alert("Dot Product: " + dotProduct3D(1, 2, 3, 2, -1, 1)); // Dot Product: 3 alert("Dot Product: " + dotProduct2D(1, 2, 2, -1)); // Dot Product: 0DOWNLOAD
