regex - Regular Expression to replace sub string in last parenthisis to strings between trignometric fun and first right closing parenthesis in Javascript -

i have string

pow((sin),(2))(4*x+5)+pow((cos),(3))(4*x+3)/pow((tan),(5))(x) 

i need as

pow(sin(4*x+5),2)+pow(cos(4*x+3),3)/pow(tan(x),5) 

what tried was

1)split expression based on operators(+,-,/,*) between pow single units.

2)extract expression between last parenthisis

3)insert extracted subexpression between first string after pow , first closing parenthis units.

what tried :-

 re="pow((sin),(2))(4*x+5)+pow((cos),(3))(4*x+3)+pow((tan),(5))(x)";     re.split(+);     re.replaceall("^[()]]{3}","\\(\\)]*\\)"); 

to frank new regular expression.

you can use following regex , replacement string:

edited

regular expression : ([a-z]+)\(\(([a-z]+)\),\(([0-9]+)\)\)\(([a-z0-9\*\+]+)\)([\*\-%\/+]*)

replacement expression : $1($2($4),($3))$5

check following code:

function cal()  {    var string = "pow((sin),(2))(4*x+5)+pow((cos),(3))(4*x+3)/pow((tan),(5))(x)";    var regex = /([a-z]+)\(\(([a-z]+)\),\(([0-9]+)\)\)\(([a-z0-9\*\+]+)\)([\*\-%\/+]*)/;    var replacement = "$1($2($4),($3))$5";    while(string.match(regex))      {        string = string.replace(regex,replacement);      }    alert(string);  }  cal();
