Scientific Calculator: Advanced Math at Your Fingertips
Our scientific calculator provides the functionality of a physical scientific calculator right in your browser. Perform complex calculations involving trigonometric functions, logarithms, exponents, roots, and more with a clean, intuitive interface.
The calculator supports both degree and radian modes for trigonometric functions, includes mathematical constants (π and e), and maintains a calculation history for reference. Memory functions let you store and recall values during complex calculations.
Available Functions
Basic Operations: Addition, subtraction, multiplication, division, percentage, and parentheses for order of operations.
Powers & Roots: Square (x²), cube (x³), any power (xʸ), square root (√), cube root (∛), and reciprocal (1/x).
Trigonometric: Sine, cosine, tangent, and their inverse functions (arcsin, arccos, arctan). Toggle INV to switch between regular and inverse functions.
Logarithmic & Exponential: Common logarithm (log base 10), natural logarithm (ln), 10^x, and e^x.
Other: Factorial (n!), constants π and e, sign change (±), and memory operations (MC, MR, M+, M-, MS).
Degrees vs Radians
Trigonometric functions can work in either degrees or radians. Degrees divide a circle into 360 parts (common in geometry and navigation). Radians divide a circle into 2π parts (common in calculus and physics).
To convert: degrees = radians × (180/π) and radians = degrees × (π/180). For example, 90° = π/2 radians ≈ 1.5708.
Using Memory Functions
MS (Memory Store) saves current display to memory. MR (Memory Recall) retrieves stored value. M+ adds current display to memory. M- subtracts from memory. MC clears memory.
FAQ
Why does sin(90) not equal 1?
Make sure you're in DEG (degree) mode. In RAD (radian) mode, sin(90) ≈ 0.894 because 90 radians is not the same as 90 degrees.
What's the difference between log and ln?
log is the common logarithm (base 10), where log(10) = 1. ln is the natural logarithm (base e ≈ 2.718), where ln(e) = 1. Use log for orders of magnitude, ln for calculus and exponential growth.
How do I calculate roots other than square/cube?
Use the power button (xʸ) with a fractional exponent. For example, the 4th root of 16 is 16^(1/4) = 16^0.25 = 2.
