Description

TinySci is a scientific calculator built for the Pebble Time 2 touch screen.

MATH THAT LOOKS LIKE MATH
What you type shows as real math as you go: fractions stack, powers rise, and the square root, pi and times signs are drawn properly. Hold on the display for a cursor to edit anywhere. Pull down from the top for a full-screen formula view.

EXACT ANSWERS
Answers come out exact when they can: 1/3 + 1/4 = 7/12, sqrt 12 = 2 sqrt 3, sin 60 = sqrt 3 / 2. The S<>D key switches between the exact form and the decimal.

SOLVE WITH THE = KEY
Type an equation in x, like x^3 - 2x = 1, and press =. No starting guess needed: it finds the roots in view and widens the search when there are none. Polynomials also get exact answers, like (1 - sqrt 5)/2, and the equation simplified. Put a y in it and it asks for a second equation, then solves the pair, curves included (a circle and a line). Three linear equations in x, y and z work too. Turn on the graph to see both sides plotted with the roots marked.

CALCULUS, AS NUMBERS OR FORMULAS
Definite integrals and derivatives at a point, or leave the limits empty to get the formula: d/dx of x^2 sin x is 2x sin x + x^2 cos x, and the integral of x sin x is sin x - x cos x + C. Factor and Expand work on polynomials: x^2 - x - 6 = (x + 2)(x - 3). Sums and products over a range too.

GRAPHING
Graph y = f(x), both sides of an equation, or curves in x and y like x^2 + y^2 = 25. Drag, zoom, and tap to read off points.

TOOLS
- Statistics: mean, median, standard deviation, min and max, and a straight-line fit with correlation
- Probability: normal distribution (density, P(Z < x) and its inverse), random numbers, prime factors
- Complex numbers: i, conjugate, real and imaginary parts, argument; polar and rectangular conversion
- Units: length, area, volume, mass, speed, temperature, pressure, energy, power and more
- Constants: physics, astronomy and math constants
- Bases: hex, octal and binary, with and, or, xor, not and shifts
- Memories A to F, plus x, y and z
- Number formats: normal, FIX, SCI and ENG

HOW TO USE IT
Swipe left or right to switch between the number and function keys, and swipe up for the solver keys. Select is =, Back deletes, Down clears and Up changes the page. Hold Up for History. Pull down from the display, or hold Down, for the formula view.
