Hello,

Back to your original question…

> [@prathmesh](#):

> How do I write cos"raised to the power 3"(t) in my processing code?

This was the fastest (667) execution in my tests for your original request:

```auto
float angle = random(0, TAU);    
float tmp = cos(angle);
float cosCubed = tmp*tmp*tmp;

```

Compared to (1127):

```auto
float angle = random(0, TAU);
float cosCubed = cos(angle)*cos(angle)*cos(angle);

```

Slowest (1275) :

```auto
float angle = random(0, TAU);
float cosCubed = pow(cos(angle), 3);

```

The numbers (ms) were the outcome of a stress test using modified code from @jeremydouglass in this topic.

Processing:

```auto
cos();

```

Is a call to Java:

```auto
(float) Math.cos(angle);

```

You can find Processing cos() and pow() here in the source code if you are adventurous to see what it calls from Java:  
[https://github.com/processing/processing/blob/master/core/src/processing/core/PApplet.java](https://github.com/processing/processing/blob/master/core/src/processing/core/PApplet.java)

Slightly faster if you call the Java Math functions directly.

🙂
