My car requires a 30% ethanol mixture. I quickly realized this was easily solvable using matrix RREF (s/o to my linear algebra prof.). This beats having to carry my TI-84 with me to the fuel pump. Also use to to calculate average octane in the fuel tank. Super handy!
I needed a to-84 calculator in a pinch last night for my homework. I was so worried I’d have to go to the store and spend the insane amount these things cost. This was only $5 and trust me it’s completely worth it. It had the functions I needed therefore making my homework so much easier! So grateful for this.
This app is an essential program to have when taking college level statistics classes to help perform distribution functions. Easy to use and great value!
Downloaded this to help with my algebra two class and it’s whole list are is broken. I spend about 20 minutes trying to get it to make a single function only for data errors to pop up and the help manual has nothing on how to do anything with the list menu.
Tried to use this for my statistics class and entered the same information in correctly and it gave me wrong answers every time!! Don’t buy ?I also can’t even find support to call to get my money back.
This calculator was programmed wrong!! I’ve gotten so many questions wrong by using this calculator! DO NOT SPEND YOUR MONEY ON IT. I just did the same problem on the calculator, one gave me 9 as an answer and the other gave me 7.5 (the correct answer). I wish I could upload a picture on here to show what I am talking about. Y’ALL I REPEAT DO NOT DOWNLOAD THIS APP!
I bought the upgrade specifically to use the rref function and it doesn’t have it... The free app does but when you click it it prompts you to upgrade and here I am full of woe.
This calculator has worked perfectly for most of my needs but I haven’t been able to figure out how to graph polar equations and there is no help in the blue question mark query area
