Scientific Calculator

What is the Scientific Calculator?

The Scientific Calculator evaluates a mathematical expression that you type into the workspace. It handles trigonometric and logarithmic functions as well as ordinary arithmetic, so you can evaluate expressions such as sin(45) + log(100) without switching apps.

How to Use the Scientific Calculator

1. Type your expression in the Expression field. The placeholder shows the form sin(45) + log(100).
2. Click Process.
3. Read the result panel, which shows the expression and its value.
4. Use Copy to copy the result, Download to save it, or Clear to start over.

Worked Example

Input: sin(45) + log(100)

Observed result: sin(45) + log(100) = 5.45607371052221

Why this value: in this tool, sin uses radians and log is the natural logarithm. Sin(45 radians) is about 0.8509 and the natural log of 100 is about 4.6052, and 0.8509 + 4.6052 = 5.4561. If you expected degrees and a base-10 log, you would get about 0.7071 + 2 = 2.7071, which is not what this tool returns.

Limitations

• Trigonometric functions use radians. There is no degrees or radians toggle in the observed workspace, so convert degrees to radians first if that is what you need.
• log is the natural logarithm (base e), not the base-10 logarithm.
• The result shows the expression and its value only. There is no history list and no step-by-step working.
• Only the functions shown by the tool were tested here (sin and log in the worked example). Do not assume every scientific function is supported without testing it.

Frequently Asked Questions

Does sin use degrees or radians?

Radians, as shown by the worked example: sin(45) + log(100) = 5.45607371052221.

Is log base 10 or the natural log?

The natural log. Log(100) contributes about 4.6052, which is ln(100), not 2.

Can I type an expression with parentheses?

Yes. The worked example uses parentheses around the function arguments, and the tool evaluates the full expression.

Does it show steps?

No. It returns the expression and the final value only.
