Full-featured scientific calculator with trigonometry, logarithms, exponents, and more. Supports degrees and radians.

Scientific Calculator

How to use

• Trig (sin, cos, tan): enter angle, then press the function. Use DEG or RAD.
• x^y: enter base, press + then type exponent, press =.
• π and e insert the constant. √, x², 1/x, log, ln apply to the current number.

About This Calculator

Perform advanced math including trigonometry, logarithms, powers, roots, and scientific notation. It is meant for STEM-style work where precision, correct order of operations, and angle mode (degrees vs radians) matter as much as the final number.

Formula

Includes standard scientific functions: sin, cos, tan, log, ln, x^y, sqrt(x)

Example

Compute sin(30 deg) + log10(100) = 0.5 + 2 = 2.5.

When to Use

STEM homework
Engineering checks
General advanced calculations

Best Practices

Confirm angle mode (degrees/radians)
Use parentheses for operation order
Keep precision high during intermediate steps

FAQ

Why are my trig results wrong?

You are likely in radians when expecting degrees, or vice versa.

When should I use ln vs log?

ln uses base e; log usually means base 10.
