TechCalc+ Calculator

TechCalc+ turns your phone or tablet into a “Swiss Army Knife” for technical math. It combines 44 calculation tools, a built-in scientific reference library, and a full Periodic Table of the Elements in one app. You can use it for everyday homework, advanced university work, lab tasks, and real engineering or science projects long after graduation.

Built for School, University, and Professional Work

TechCalc+ targets anyone who needs reliable results without jumping between multiple apps. You can run quick checks during class, solve complex assignments at home, and keep the same toolkit available when you start working in research, development, finance, or engineering.

Main Calculator Modes (From the Main Menu)

TechCalc+ groups its most-used tools into dedicated modes so you can choose the right environment immediately:

• Graphing tools for Functions, Implicit and Parametric equations, XY scatter plots, and 3D surface plots
• Matrix operations, including inverse, transpose, determinant, cofactor, adjugate, trace, rank, eigenvalues/eigenvectors, and decompositions (LU, Cholesky, QR, SVD)
• Complex number calculations in Cartesian and Polar form, including support for Euler-style representations
• Quick Formulas, featuring dozens of classic science formulas plus the ability to save your own custom formulas
• Quick Converter for fast unit and category conversions
• Time Calculator for time-based calculations
• Equation Solver for linear equations, polynomial roots, exponential exponents, inequations, polynomial factorization, GCD/LCM of polynomials, binomial expansion, and vector arithmetic
• Calculus tools with symbolic algebra, derivatives, integrals (definite and indefinite), Taylor series, and limits
• Financial calculators covering interest, cash flow, amortization, annuities, margin/markup, break-even, depreciation, bonds, date calculations, interest conversion, and options “Greeks”

Periodic Table Included

TechCalc+ doesn’t treat chemistry as an afterthought. It includes the Periodic Table, so you can quickly look up essential element data while you calculate formulas, masses, or reaction steps.

Core Features You Can Use Across Tools

TechCalc+ supports a wide range of functions that students and professionals use constantly:

• Full trigonometry with radians, degrees, or gradients
• Powers, roots, logarithms, and antilogarithms
• Factorial, modulus, and random-number functions
• Number theory tools such as HCF, LCM, and prime factorization
• Coordinate helpers like Pol() and Rec()
• Permutations (nPr) and combinations (nCr)
• Extensive statistics functions (30 options)
• Broad conversion categories (35 groups)
• A library of physical and astronomical constants (52 total)
• Fraction mode for exact fractional work
• 20 memory registers in every calculation mode
• Detailed calculation history so you can review and reuse previous work
• In-depth help and reference pages
• Strong settings and customization options to fit your workflow

Reference Section: Extra Calculators and Converters

The reference section expands TechCalc+ beyond a typical calculator. It includes practical utilities such as:

• ASCII and Roman numeral converters
• Aspect ratio, percentage, proportion, and unit price comparison tools
• Chemical helpers like empirical formula calculations, molecular weight, and equation balancing
• Engineering and science calculators for RLC circuits, barometric formula, humidity, wind chill, ephemerides, interpolation, polygon area, and geodetic distance
• Computing and networking tools like IEEE 754 conversion, number base conversion, fractional bits, and IP subnet calculation
• Statistics tools, including grouped data and linear regression analysis
• Everyday utilities such as BMI, feet-and-inches, and bicycle tire pressure calculations

You can also move any of these reference tools to the main menu, which helps you build a layout that matches what you use most.

Reference Library: Tables, Rules, and Technical Notes

TechCalc+ also acts as a compact study and field reference. It includes:

• Physical laws and mathematical tables
• Elementary and linear algebra notes
• Trigonometric identities
• Differentiation and integration rules
• Statistics formulas and vector mathematics
• Metric system naming conventions and cooking temperature scales
• Beaufort wind scale information

Customization and Workflow Control

TechCalc+ lets you tailor the experience through settings, saved formulas, menu organization, memory registers, and history tracking. You can shape the app into a fast “daily driver” for basic tasks or a deeper toolkit for advanced coursework and technical problem-solving.
