How do I calculate sine of 30 degrees?

Press the DEG mode button, enter 30, then press sin. The result displays 0.5 instantly.

What is the value of log(100) base 10?

Enter 100, press the log button. The answer is exactly 2.

Can I use keyboard input instead of clicking buttons?

Yes. Type numbers, operators (+, -, *, /), and functions directly. Press Enter for equals, Backspace for delete, and Escape to clear.

Does this calculator support scientific notation?

Absolutely. Use the EXP button or type 'e' (e.g., 1.5e3 for 1500). Results automatically switch to scientific notation for very large or small numbers.

Frequently Asked Questions About Scientific Calculator

Got questions about using trig functions or constants? Read the answers below.

Q.How do I change between Radians and Degrees?

Toggle the "RAD/DEG" key on the layout. The indicator on the screen will update dynamically to show DEG (Degrees) or RAD (Radians).

Q.What is the difference between log and ln?

The "log" key calculates the common base-10 logarithm. The "ln" key calculates the natural logarithm based on the constant e.

Q.Does it support keyboard inputs?

Yes, standard numeric values, arithmetic signs (+, -, *, /), and parentheses can be entered using physical keyboards.

Q.How is data security handled?

CanvaTools evaluates everything inside client-side JS without submitting calculations to any external servers, ensuring 100% local safety.
