Atan2

Function: atan2 (<y>, <x>) - yields the value of atan(<y>/<x>) in the interval -%pi to %pi.

aInitialValue_num: 1.0;
aFinalValue_num: 1.0;
aDuration_num: 4.0;
lMaxNormalizedDeviation_num: 0.14;
slow: 1.5;
plot2d(-cos(aCurrentTime_num / aDuration_num * %pi), [aCurrentTime_num,0,aDuration_num]);
plot2d(aInitialValue_num + aCurrentTime_num * atan2(aFinalValue_num - aInitialValue_num, aDuration_num) + lMaxNormalizedDeviation_num * 0.5 * (1 - cos((aCurrentTime_num / aDuration_num)^slow * 2 * %pi)),[aCurrentTime_num,0,aDuration_num]);
