# WaveringDotsAround

For the MinaCoding Prompt: New Function. I will be coding: WaveringDotsAround with Tixyland & SonicPi. The new functions that I have introduced to my workflow are the following:

• Math.imul() : Returns the result of the 32-bit integer multiplication of x and y.

• Math.sinh(): Returns the hyperbolic sine of x.

• Math.cbrt(): Returns the cube root of x.

• Math.hypot(): Returns the square root of the sum of squares of its arguments.

• lgamma(x) → [float, -1 or 1]click to toggle source Calculates the logarithmic gamma of x and the sign of gamma of x. (Ruby)

• gamma(x) → Float**:** Calculates the gamma function of x.

## Design Process

• Used the above-mentioned functions in both the audio and visuals

• The dots are overlayed sketches done by TixyLand

• The sounds are coded in SonicPi using a concept of shadow maths and colour shuffling, where in this case the sounds are made through the values of different reds. As well as their shadow/shuffle counterparts to add variance to the soundscape. So when watching, you are experiencing both red as a colour and a sound. With the addition of new math functions, the shadows have been reimagined

## Code

### Tixyland

``````imul(t,y)/(sinh(t/i)+tan(t/y^3)+cos(t/x))/sqrt(i/t) + cbrt(y/t)
``````

### SonicPi
