I am a physicist, and as a physicist I am naturally reasonably curious. I have bought 7 ChatGPT apps, and bought the "best" packages so that the products would appear as similar as possible so that the "scientific experiment" would be as correct as possible. 10 different math calculations of varying difficulty were performed (all apps were completely terminated between each calculation) It turned out that this app was the most correct, giving correct answers in 80% of cases. The mathematical calculations were as follows trigonometry using cosine, sine and tangent - then control calculated by ChatGPT with cosine^-1 ect, geometry, advanced calculus, Newton's universal law of gravitation, relativistic calculations (Einstein's theory of relativity, however NOT differential geometry) All calculations was manually calculated and checked by me (Master's degree in theoretical physics, general relativity), as well as a mathematician (Master's degree in theoretical mathematics). Best Wishes, Sondre, master of science, physics.
Thank you so much for kind words and leaving the best review for our app BrutusAI which is Open ai ChatGPT powered unlimited macos app. 💙 You can also focus when starting new chat and select academic sources for finding journals related answer.Hope this helps!
