Symbolab is an answer engine [1] that provides step-by-step solutions to mathematical problems in a range of subjects. [2] It was originally developed by Israeli start-up company EqsQuest Ltd., under whom it was released for public use in 2011. In 2020, the company was acquired by American educational technology website Course Hero. [3] [4]
The TI-58 has half the memory of the TI-59 and supports up to 480 program steps or 60 memories. It competed with the HP-34C. The TI-58 and TI-59 calculators have variable-length instructions. Some keypresses are merged into one programming step, so that instructions from one to eleven keypresses are stored in one to six programming steps.
A multiple sequence alignment is taken of this set of sequences by inserting any amount of gaps needed into each of the sequences of until the modified sequences, ′, all conform to length {=, …,} and no values in the sequences of of the same column consists of only gaps. The mathematical form of an MSA of the above sequence set is shown below:
On a single-step or immediate-execution calculator, the user presses a key for each operation, calculating all the intermediate results, before the final value is shown. [ 1 ] [ 2 ] [ 3 ] On an expression or formula calculator , one types in an expression and then presses a key, such as "=" or "Enter", to evaluate the expression.
Smaller programmable model with programs up to 49 steps. Version HP-25C was first calculator with "continuous memory". HP-27S: 1988 The first HP pocket calculator to use algebraic notation only rather than RPN. It was a "do all" calculator that included algebraic solver like the HP-18C, statistical, probability and time/value of money ...
Some 50 employees joined Amplify. Desmos Studio was spun off as a separate public benefit corporation focused on building calculator products and other math tools. [7] In May 2023, Desmos released a beta for a remade Geometry Tool. In it, geometrical shapes can be made, as well as expressions from the normal graphing calculator, with extra ...
You might start the year hoping to lose a few pounds or get a few more steps in, but it's also a good time to take stock of your home's emergency readiness, including fire safety. So while you're ...
The compass is assumed to have no maximum or minimum radius, and is assumed to "collapse" when lifted from the page, so it may not be directly used to transfer distances. (This is an unimportant restriction since, using a multi-step procedure, a distance can be transferred even with a collapsing compass; see compass equivalence theorem.
