SciCalcGuide: Scientific Calc

SciCalcGuide is a scientific calculator for high school and college students who want to understand their answers, not just get them.

• Enter whole expressions like 2(3+4)^2 or 3sin(30)+ln(e) with correct order of operations
• Use trig, inverse and hyperbolic functions with a Degrees/Radians switch
• Work with logs in base 10, base e, or any base, plus square, cube, and n-th roots
• Switch between a compact Standard keypad and the full Scientific layout
• Reopen past results from history, reuse the last answer, or copy the history out
• Read clear formula notes on trig, logs, powers, percentages, and constants, each with a Try It example
• Convert length, mass, area, time, and temperature and send the result to the calculator
• Plot y = f(x) with pan and zoom and read a table of values
• Solve quadratic, polynomial and 2×2 or 3×3 linear equations, with the steps shown
• Save variables and your own functions such as f(x) and use them in any expression
• Use nPr, nCr, gcd, lcm, mod, round and random numbers
• Copy any result with one tap

When an expression cannot be worked out, a plain message tells you exactly why.
