Some Math formulas written in JS

Square

Area

SquareArea(s){
  let area = s*s;
  return area;
}

Perimeter

SquarePerimeter(s){
  let perimeter = 4*s;
  return perimeter;
}

Circle

Area

CircleArea(r){
  let area = Math.PI*r*r;
  return area;
}

Perimeter

CirclePerimeter(r){
  let perimeter = 2*Math.PI*r;
  return perimeter;
}

Triangle

Area

TriangleArea(b,h){
  let area = b*h/2;
  return area;
}

TriangleArea(a,b, angleACB){
  let area = a*b*Math.sin(angleACB)/2;
  return area;
}

Trigonometry

SinAplusB(A,B){
  let result = Math.sin(A)*Math.cos(B)+Math.sin(B)*Math.cos(A);
  return result
}
