How to Use This Tool
Step-by-step guide to get the best results
1

Enter your expression

Type numbers and operations using the on-screen buttons or your keyboard to build the math expression you want to solve.

2

Use function buttons

Tap sin, cos, tan, ln, log, or other function keys to insert them into your expression at the cursor position.

3

Toggle angle mode

Switch between degrees and radians using the DEG/RAD toggle before evaluating trigonometric expressions.

4

Press equals

Hit the equals button to evaluate the full expression and display the result on screen.

5

Review history

Scroll through the calculation history panel to see previously computed results during your session.

Pro Tips
1

Switch to radian mode when working with calculus problems involving pi.

2

Use parentheses liberally to control the order of operations in complex expressions.

3

Check your angle mode before computing trig values to avoid incorrect results.

4

Use the exponential button for scientific notation, such as entering 6.02e23 for Avogadro's number.

Frequently Asked Questions
What trigonometric functions does this calculator support?

It supports sin, cos, tan and their inverse functions arcsin, arccos, and arctan. You can toggle between degree and radian mode to match the unit your problem requires.

Can I use this calculator on my phone?

Yes, the calculator runs entirely in the browser and works on phones, tablets, and desktops. The responsive layout adapts to smaller screens so buttons remain easy to tap.

Does it handle parentheses and order of operations?

Yes, you can nest parentheses to any depth and the calculator follows standard mathematical order of operations. Exponents are evaluated before multiplication, which is evaluated before addition.

What constants are built in?

The calculator includes pi, Euler's number e, the golden ratio, and the speed of light among other commonly used constants. Tap the constants button to insert them directly into expressions.

Is the calculation history saved between sessions?

No, the history is stored only during the current browser session. Once you close the tab or refresh the page, the history is cleared. Copy any results you need to keep before leaving.
