Using the Scientific Calculator
This scientific calculator extends ordinary arithmetic with the functions students, engineers, and analysts rely on every day: trigonometry, logarithms, exponential powers, square roots, and factorials. Tap the keys to build an expression in the display, then press the equals key to evaluate the whole thing at once. You can chain several operations together and use parentheses to control exactly how they are grouped.
Supported Operations
- Trigonometry: sin, cos, and tan, with a DEG / RAD toggle so angles are read in the unit you expect.
- Logarithms: log for base-10 and ln for the natural logarithm based on the constant e.
- Powers and roots: the x^y key raises a number to any power, and the square-root key returns the root of a value.
- Factorials and constants: x! multiplies every whole number up to your input, while π and e insert their precise mathematical values.
Degrees Versus Radians
Trigonometric functions can interpret angles in two ways. Degrees divide a circle into 360 parts and are common in geometry and everyday measurement, while radians measure angles by arc length and appear throughout calculus and physics. Set the toggle before you calculate, because sin(30) returns 0.5 in degree mode but a very different value in radian mode.
Order of Operations
The calculator follows standard mathematical precedence: expressions inside parentheses are resolved first, then powers, then multiplication and division, and finally addition and subtraction. When you are unsure how a long expression will be grouped, wrap the part you want evaluated first in parentheses to remove any ambiguity.
Practical Uses
Use it to check homework, work through trigonometry and logarithm problems, compute growth with powers, or evaluate probability questions that rely on factorials. Because every calculation runs instantly in your browser, you can experiment freely and correct mistakes with the clear and backspace keys without losing your place.
