A scientific calculator is an advanced mathematical tool that goes beyond basic arithmetic operations. Our free online scientific calculator from CalculusHub provides a comprehensive set of functions including trigonometry, logarithms, exponents, factorials, and statistical operations. Whether you’re a student, engineer, scientist, or professional, this tool delivers precise calculations for complex mathematical problems.

Mathematical Functions and Capabilities

At CalculusHub, we’ve designed our scientific calculator with mathematical precision and user experience in mind. Our calculator includes:

Trigonometric functions – sine, cosine, tangent and their inverses
Logarithmic functions – common log (base 10) and natural log (base e)
Exponential functions – powers, roots, and constants like π and e
Statistical operations – factorial, percentage calculations
Memory functions – store, recall, and add to memory for complex calculations
