Frequently Asked Questions

What is a Scientific Calculator?

A scientific calculator is a type of calculator designed to handle complex mathematical operations beyond basic arithmetic. Our online Scientific Calculator includes functions for trigonometry, logarithms, exponents, and more.

Is this calculator free to use?

Yes, our Scientific Calculator is completely free to use with no limitations or hidden costs.

Can I use this calculator on my mobile device?

Yes, our calculator is designed to be responsive and works well on smartphones, tablets, and desktop computers.

How accurate are the calculations?

The calculator uses JavaScript's built-in math functions, which are accurate for most everyday calculations. However, for critical scientific or financial calculations requiring extreme precision, we recommend using specialized software.

Are the trigonometric functions in degrees or radians?

The trigonometric functions (sin, cos, tan) in our calculator use degrees as input. For example, sin(90) will calculate the sine of 90 degrees.

What is the "M+" and "MR" functionality?

The memory functions allow you to store and recall values:

• M+ (Memory Add): Adds the current displayed value to memory
• MR (Memory Recall): Displays the value currently stored in memory
