함수, 극좌표, 매개변수 그래프, 방정식 풀이 및 종합 통계 분석을 지원하는 그래프 계산기 앱입니다. 실제 84 그래프 계산기와 유사한 UI를 제공하는 그래프 계산기입니다. ◉ 그래프 계산기 - function, polar, parametric 그래프를 지원합니다. - MODE를 눌러 Graph mode를 선택한 뒤 Y=를 눌러 그래프 편집기를 엽니다. GRAPH를 눌러 함수를 그립니다. - 대화형 및 수동 추적 모드 지원. - 함수 그래프의 교점, 근, 극값(국소 최댓값/최솟값)을 표시합니다. - 함수 그래프의 도함수를 표시합니다. - function 및 polar 그래프의 접선을 표시합니다. - 점 집합에 대해 최적 적합 직선을 제공합니다. - TABLE은 선택한 그래프의 값 표를 생성합니다. - CALC는 선택한 그래프의 최솟값, 최댓값, d/dx, 적분을 계산합니다. ◉ 공학용 계산기 - 기호 연산을 위한 CAS(Computer Algebra System)를 포함합니다. - 실제 83 및 84 그래프 계산기의 모든 기능을 지원합니다. - 기본부터 고급 수학 기능까지: 복소수, 확률, 각도, 관계 연산, 논리 연산, 행렬 및 벡터 연산. - 사용자 지정 계산기 함수를 정의할 수 있습니다. ◉ 방정식 풀이기 (ALPHA ENTER를 눌러 SOLVER 메뉴 열기) - Auto Solver 모드로 다양한 방정식을 풀며, 기호 근도 제공할 수 있습니다. - 2차, 3차, 4차, 5차 방정식을 풉니다. - 최대 5개 미지수의 연립방정식을 풉니다. ◉ 통계 - 1‑Var Stats: 일변량 통계를 계산합니다. - 2‑Var Stats: 이변량 통계를 계산합니다. - LinReg(ax+b): 데이터에 선형 모델을 적합합니다. - QuadReg: 데이터에 2차 모델을 적합합니다. - CubicReg: 데이터에 3차 모델을 적합합니다. - QuartReg: 데이터에 4차 모델을 적합합니다. - LinReg(a+bx): 데이터에 선형 모델을 적합합니다. - LnReg: 데이터에 로그 모델을 적합합니다. - ExpReg: 데이터에 지수 모델을 적합합니다. ◉ 추론 통계 및 분포 - Z‑Test, T‑Test, 2‑SampZTest, 2‑SampTTest, 1‑PropZTest, 2‑PropZTest, Z‑Interval, T‑Interval, 2‑SampZInt, 2‑SampTInt, 1‑PropZInt, 2‑PropZInt, Chi‑square Test, Chi‑square GOF Test, 2‑SampFTest, LinRegTTest, LinRegTInt, ANOVA. - 정규, Student’s t, Chi‑square, F, 이항분포 등 모든 분포 함수를 지원합니다. ◉ Calculator 84 Premium Premium으로 업그레이드하면 위의 모든 기능(고급 수학 기능, 통계, 추론 통계 및 분포 등)을 사용할 수 있습니다. 3가지 구독 옵션 제공: - 1개월 구독 - 1년 구독 - 평생 이용권 구독 결제는 구매 확인 시점과 각 갱신 기간 시작 시 iTunes 계정으로 청구됩니다. iTunes 계정 설정에서 언제든지 취소할 수 있습니다. 다음 결제가 청구되지 않도록 하려면 현재 기간 종료 24시간 이전에 취소해야 합니다. 취소는 현재 기간 종료 다음 날부터 적용되며, 서비스는 무료 버전으로 전환됩니다. 이용 약관: https://calc84-efd3d.firebaseapp.com/tos.html 개인정보 처리방침: https://calc84-efd3d.firebaseapp.com/privacypolicy.html

It’s GREAT!

Just like the real thing, and I have two Ti-84 calculators. I’m only giving ‘5’ stars because I do believe it could use some polishing up to ‘appear’ like the real thing, and I do believe that the creators of this app might be surprised at how many more apps they would ‘sell’. I always ‘purchase’ to get rid of ads, which are totally annoying. You would sell FAR more if you gave your buttons more ‘depth’, with dark tiny spacing to define the button away from its frame; the way it is, currently, is way too duo-dimensional. Add more depth and shadowing to where the cosmetics are more realistic and I would wager that your sales would increase to where people would pay for your product more than just wanting the ‘free’ version. Regardless, this is an excellent app - I purchased the ‘Lifetime’ upgrade!

Annoying pop ups requesting reviews, no help/instructions and operations changes between ti84

Overall this calculator works pretty well. However are no instructions on how to use it, so if you're familiar with a TI84 for instance, you can figure it out but its not identicial in operation. There is a 'help' section but if you click it, it says there is nothing there. Also the app continues to do a pop up asking for a 5 star review, so I'm leaving a 2 star as a result. I paid money for this app, I'm not going to be bugged about reviews after paying money. One minor issue is the alpha button's color does not match the alpha button key options above the keys. This is usually matching. My overall review is yes this app works, it'll get the job done, but if you want a computer version of the TI84, look elsewhere as some of the commands within this are complicated and there is no guidance.Calculator unable to handle equation 14!/(3!11!). Gives the error message "error: syntax error" . Whereas my portable regular TI84 calculator can handle the problem without issue.

Out of what I know it lets me do almost everything on a normal expensive graphing calculator, but for free. Some things are locked unless I think until u buy the premium. But barely anything is locked. There are all of the buttons on a normal graphing calculator. You can click the same buttons to get the same outcome like a normal calculator. This makes it very less complicated than other calculator apps. Although, during some tests I am not allowed to use a phone which makes sense. I can only use a real calculator. That’s the one thing that I cannot use it for.

Beware serious bugs

I have been generally impressed with the capability of this calculator, and it is my "go to" calculator for vector operations.However, it has some serious and unexpected bugs. Some polar-rectangular conversions have unexplainable errors using particular angle values, and some list functions provide grossly wrong answers (wrong sign, wrong magnitude).Update: The author responded with a work-around for the polar conversion issue. The multiplication of lists still gives unexpected results
