Scientific Calculator Guide
Use the scientific calculator for arithmetic, powers, roots, logarithms, trigonometric functions, and other common mathematical operations. Enter expressions carefully and review the selected angle mode before using sine, cosine, or tangent.
Degrees and radians
Trigonometric results depend on the angle mode. Use degrees for most school and everyday angle problems, and radians when working with calculus, physics, or formulas that specify radians.
Check order of operations
Parentheses make the intended calculation clear. Review signs, decimal points, exponents, and brackets before copying a result into a technical or academic calculation.
