How to cube a sine/cosine function in processing

[glv]

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:

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

Compared to (1127):

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

Slowest (1275) :

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:

cos();

Is a call to Java:

(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:

Slightly faster if you call the Java Math functions directly.
