Question 1

What functions does the scientific calculator support?

Accepted Answer

This calculator supports trigonometric functions (sin, cos, tan and inverses), logarithms (log, ln), exponentials, square roots, power functions, factorials, and constants like π and e.

Question 2

What is the difference between radians and degrees?

Accepted Answer

Radians and degrees are units for measuring angles. 1 radian = 180/π ≈ 57.3°. Full circle = 2π radians = 360°. Scientific calculations typically use radians; everyday use often uses degrees.

Question 3

What is the order of operations (PEMDAS/BODMAS)?

Accepted Answer

Operations are evaluated in order: Parentheses/Brackets, Exponents/Orders, Multiplication and Division (left to right), Addition and Subtraction (left to right). This ensures consistent calculation results.

Question 4

What is logarithm and when do I use it?

Accepted Answer

A logarithm is the inverse of exponentiation. log₁₀(x) finds the power of 10 that equals x; ln(x) is the natural log (base e). Used in science, engineering, finance, and data analysis.
