What is a Scientific Calculator?
A scientific calculator is an advanced calculator that performs mathematical operations beyond basic arithmetic. It handles trigonometric functions (sin, cos, tan), logarithmic functions (log, ln), exponentiation, roots, and factorials — making it essential for students in algebra, calculus, physics, and engineering.
This online scientific calculator works exactly like a physical Casio or Texas Instruments unit, with the added convenience of being accessible from any device. All calculations run in your browser — nothing is sent to any server.
Supported Functions
Trigonometric (Degrees)
sin(θ) cos(θ) tan(θ)
All trig functions use degrees. Example: sin(90) = 1, cos(60) = 0.5.
Logarithmic
log(x) = log₁₀(x) ln(x) = logₑ(x)
Powers & Roots
x² xʸ √x 1/x
Special
n! (factorial) π = 3.14159... e = 2.71828...
Usage Examples
Pythagorean Hypotenuse
sqrt(3^2 + 4^2) = 5
Compound Interest Factor
1.05^10 = 1.6288946...
Factorial
10! = 3628800
People Also Ask
What functions does this scientific calculator support?
This calculator supports trigonometric functions (sin, cos, tan in degrees), logarithms (log base 10 and natural log ln), square root (√), power/exponent (xʸ), factorial (!), percentage (%), and constants π and e.
Does this calculator use degrees or radians?
Trigonometric functions (sin, cos, tan) use degrees by default, which is the standard for most academic use. For example, sin(90) = 1.
Can I chain operations together?
Yes, you can build complex expressions using parentheses and chain multiple operations. After pressing =, typing a number starts a new calculation, while typing an operator continues from the result.
