FlowCE 2.4

FlowCE 2.4 adds logs with any base: log₂(8) is drawn as textbooks write it, typed from the math
key or the log key, with exact answers and steps for log equations.

Install from the website, or send FlowCE.b84
with TI Connect CE and run INST. On a TI-83 Premium CE, send FlowCE.b83 instead.

• Log with any base: math, then 0 puts log□(□) on the line with the caret in the base, as
  the TI-84's logBASE: type the base, ▶, the number. Or press log, type the number, a comma and
  the base: log(8,2) is drawn log₂(8). The math card's new last row also has the n-th root and eˣ.
• Exact answers: log₄(8) is 3/2, log₈(2) is 1/3, log₂(1/8) is −3; a number that is not a power
  of the base gives ln(10)/ln(2) (≈ 3.32193). In 2.3, log 8 , 2 gave two answers (the logs of 8
  and of 2), and log₄(8) was ln(2)/ln(4)+1.
• Log equations keep their base on the steps page: log₂(x+1) = 3, its exponential form,
  x = 7.
• Algebra's steps show for what you type: a power typed with ^ or x² (x²−5x+6=0,
  factor(x²−5x+6), (x³−1)/(x−1)) hid the steps of equations, factoring and polynomial division;
  enter after the answer shows them now. Calculus was not affected.
• TI-83 Premium CE: the trig key shows sin, cos, tan and their inverses to choose from (1 to 6;
  enter: sin).
• Graph: X,T,θ,n switches the readout between the equation and the slope m (the radius R
  with the osculating circle).
• Keys: a function key right after a letter multiplies: a, then sin, is a·sin, not arcsin.
• Menus open faster.

Checks

• On an emulated TI-84 Plus CE: the 898 regression problems give the same answers as 2.3 (none
  hung, 2% less time in all), and so do the 71 applications problems and the equations, statistics
  and quartic sets; interrupting with on, out of memory (8/8), 101 screen checks (the same but for
  the version, the math card's new row and the graph's X,T,θ,n hint), 29 ways through the menus.
• The log with a base: 46 cases of typing, arrows, delete and answers (the math card, the log
  key, log(8,2) typed, bases 1/2 to 10, log equations and their steps), and the 2D editor's host
  tests. Algebra's steps: 14 problems typed with the keys (quadratics, cubics, a quintic, factoring,
  divisions, rational and linear equations): each offers steps and shows them, or offers none.
  On a TI-83 Premium CE build: the trig key's six functions.
• The release file installed on a fresh calculator (arTIfiCE, INST, the reset button).
