Version 1.22 (7/3-2020)
This release is mainly about differential equations
– Improved differential equation solver with initial conditions
– Solves some problems with directional field graphs.
– binomial sheets slightly improved.

Denne version handler primært om differentialligninger
– Forbedret differentialligningsløser for differentialligninger med startbetingelser
– Retningsfelt omdøbt til hældningsfelt
– Løst nogle problemer med plotning af hældningsfelt.
– uafh. variabel kunne kun være y
– Nogle gange blev hele løsningskurven ikke tegnet
– binomialarket / binomialtest kan man nu indtaste enten observeret middelværdi eller observeret p-værdi

Version 1.21 (29/2-2020)
Dette er en mindre opdatering der retter fejl
– Middelværdi og spredning på statistikarket for grupperede observationer blev ikke beregnet korrekt
– Ved eksponentiel regression på Excel-graf arket vises nu også på formen y=b*a^x
– Student t-fordelingen åbnede ikke
– Hjælp til Maxima kommandoer virkede ikke
– Nogle udtryk med pi virkede ikke på Mac
derudover nogle få mindre rettelser

Version 1.20 (10/2-2020)
Denne version lukker nogle huller i forhold til pensum i den nye læreplan.
– Statistik-regnearket opdateret
– Binomialregnearket tilføjet usikkerhedsberegninger
– Ved regression i graf-regnearket kan residualerne overføres direkte til statistikarket.
– Understøttelse af ny notation til partielt afledte fx: f_yx”(x,y)
– Understøttelse af nabla-operator
– I forrige version manglede der understøttelse af nogle enheder. Det er nu rettet.

Version 1.19 (20/11-2019)

– Resolves af number of old and new CAS related problems introduced in the previous version.
Vector and matrix calculations functional again
Improvements in 1st order Differential equations
Improvements in numerical integration
The number of significant figures are now correct
Error handling improved
many smalller improvements to CAS
– Codesigning of Windows-installer and all macro-files ensure smoother installation. Less virus-warnings and macro warnings.
