Radian to degree: var Degrees = Radian * (180 / Math.PI)
Degree to transform var bval=Math.sin(45*Math.PI / 180);
Transform to angle var angle = Math.round(Math.asin(bval) * (180/Math.PI));
Degree to radian: var Radians = Degree * Math.PI/180
The above steps tried with the below code with values "-3.17934" & "-0.9998"
`<script>
console.log("--------------------------------");
//var rad2="-3.17934";//-3.17934
var rad2="-0.9998";//-0.9998
console.log("First radian: "+rad2);
var rad2angle = rad2 * (180/Math.PI);
console.log("2 rad2angle: "+rad2angle);
var tt = Math.sin(rad2angle*Math.PI / 180);
console.log("3 To Transform: "+tt);
var t2angle = Math.round(Math.asin(tt) * (180/Math.PI));
console.log("2 t2angle: "+t2angle);
var angle2radian = t2angle * Math.PI/180;
console.log("Last radian: "+angle2radian);
</script>`
Thanks in Advance.
I tried with above code given in detail area.
I have modified the code & i got the proper output. Thanks everyone.
<script>
console.log("--------------------------------");
var rad2="-0.9998";
console.log("1- Radian Value: "+rad2);
var rad2angle = rad2 * (180/Math.PI);
console.log("2- Radian to Angle: "+rad2angle);
var cos=Math.cos(rad2angle*Math.PI / 180);
var sin=Math.sin(rad2angle*Math.PI / 180);
var catrans = [];
const trans = [cos, sin, -sin, cos, 0, 0];
console.log("3- Form Transform: "+trans.toString());
var tt= Math.atan2(sin,cos);
var angle2radian = tt * 180/Math.PI;
console.log("2- Transform to Angle: "+angle2radian);
console.log("1- Angle to radian: "+tt);
