Scientific Calculator

Trigonometry

sin²(x) + cos²(x) = 1

tan(x) = sin(x) / cos(x)

Logarithms

log(a*b) = log(a) + log(b)

ln(e^x) = x

Calculus Rules

Derivatives

d/dx(x^n) = n*x^(n-1)

d/dx(sin x) = cos x

Integrals

∫x^n dx = (x^(n+1))/(n+1)

∫(1/x) dx = ln|x|

Matrix Operations

Addition

A + B = [aᵢⱼ + bᵢⱼ]

Multiplication

(AB)ᵢⱼ = Σ aᵢₖ * bₖⱼ

Determinant (2x2)

|A| = ad - bc

Your Go-To Online Scientific Calculator

Welcome to the Solvr Scientific Calculator, a precision tool hosted by Oniqutes.com. While basic calculators handle simple arithmetic, our advanced scientific engine is built to support high-level mathematics, physics, and engineering problems. Whether you are a student tackling algebra homework or a professional needing quick computations, this tool provides the functionality of a physical handheld calculator directly in your web browser.

Key Capabilities & Functions

  • Order of Operations: Our algorithm respects standard mathematical rules (PEMDAS), ensuring complex equations with parentheses are solved in the correct sequence.
  • Constants: Quickly access Pi (π) and Euler's number (e) for high-precision calculations.

Why Use a Web-Based Calculator?

Physical calculators can be expensive and easy to lose. The Solvr suite offers a free, accessible alternative that requires no software downloads or installation. It is optimized for both desktop and mobile devices, ensuring you have powerful computational tools at your fingertips whenever you need them.

Frequently Asked Questions

Common questions about our mathematical tools

Is this calculator free to use?
Yes, all tools on Solvr are completely free to use for students, professionals, and anyone who loves math.
How do I calculate derivatives?
Select the "Derivatives" tab, enter your function using 'x' as the variable (e.g., 'x^2 + 5*x'), and click Calculate. The tool provides the value and a table of values around the point.
Can I solve systems of linear equations?
Yes, strictly for 2-variable systems, you can use the Equation Solver. For matrices, use the Matrix Calculator to perform operations like addition and multiplication.
Does it support complex numbers?
Currently, the Quadratic Equation solver supports complex roots (showing 'i'). Other calculators primarily operate on real numbers.
