Scientific Calculator Guide
Understanding Scientific Functions
A scientific calculator goes beyond basic arithmetic to handle complex mathematical operations used in science, engineering, and advanced mathematics.
Worked Examples
Example 1: Trigonometry
Calculate: sin(30°) + cos(60°)
sin(30°) = 0.5
cos(60°) = 0.5
Result: 0.5 + 0.5 = 1
Example 2: Logarithms
Calculate: log(1000) × ln(e²)
log(1000) = 3 (since 10³ = 1000)
ln(e²) = 2 (natural log of e²)
Result: 3 × 2 = 6
Example 3: Compound Expression
Calculate: sqrt(144) + pow(2,5) - fact(3)
sqrt(144) = 12
pow(2,5) = 32
fact(3) = 6
Result: 12 + 32 - 6 = 38
