Known ClassCalc Bugs

Below we've listed some of the known ClassCalc bugs. We're sharing this document so you, as the teacher or student, can be prepared ahead of time, and have minimum surprises while calculating and computing. Please note that we are always working hard on fixing as many of these as possible, its just a matter of which order.

If any of the listed bugs are important to your curriculum, let us know, and we'll bump it to the top of the list.

• Known Calculator Crashes

  • Graphing "x!" or anything similar
  • On slower phones, the app may crash with extremely large/complicated computations, such as graphing the polar function: "r=sec(3^(2theta)-6)"

• Calculator Bugs

  • Calculus

    1. The definite Integral of exponential equations with decimals in the base aren't working properly. As seen below, 2.5^x gives an incorrect answer, whereas 3^x gives the correct answer.

  • Symbolic Calculus 
    1. The integral of log(x) or ln(x) (or anything contains log(x) or ln(x)) displays incomplete graphs for negative values of x

    2. The indefinite integral of log(x) (or anything that contains log(x) will give a correct answer, but in a very confusing format

    3. The indefinite integral of e^x (or anything that contains e^x) will give a correct answer, but in a very confusing format

• Classrooms Bugs

  • Test Mode

    • There are certain equations that can crash the calculator, turning the app into a blank white screen.
    • If the calculator crashes for a student during Test Mode, the student will need to exit the test (with the teachers permission), and ask the teacher to resend an invite.
