NaN in a mathematical equation-CodePudding

So I got this mathematical equation and I need to write it in pure JS using the Math object obviously.

I looked up at the docs about the required methods to solve it, but I get the NaN in the console when I output the result.

I suppose it's my stupid brain that cannot solve this correctly

Here's the code:

let
  z = 5
, x = 10
, y = 2
, b = Math.cos(Math.pow(2)) * z   Math.tan(2 * x)   Math.abs(y)
  ;
console.log(b);

CodePudding user response：

let
  z = 5
, x = 10
, y = 2
, b = Math.cos(z)**2   Math.tan(2 * x)   Math.abs(y)
  ;
console.log(b);

CodePudding user response：

You are using Math.pow() incorrectly. The method takes two arguments, the base and the power.

I believe your expression b should look like this:

b = Math.pow(Math.cos(z), 2)   Math.tan(2 * x)   Math.abs(y)
