Full-featured scientific calculator with trigonometry, logarithms, and memory functions
Calculate sin(45°): Set mode to DEG, press sin, type 45, close parenthesis, press =. Result: 0.7071 (which is √2/2).
Calculate log(1000) + 2³: Type log(1000)+2^3, press =. Result: 11 (since log₁₀(1000) = 3 and 2³ = 8).
Calculate √(144) × π: Type √(144)×π, press =. Result: 37.699 (since √144 = 12 and 12 × π ≈ 37.699).
DEG (degrees) uses the 360° system familiar from everyday measurements. RAD (radians) uses the mathematical standard where a full circle is 2π. Most everyday calculations use degrees, while advanced math and physics typically use radians.
ln is the natural logarithm (base e ≈ 2.718), commonly used in calculus and science. log is the common logarithm (base 10), used in engineering and everyday calculations. For example, ln(e) = 1 and log(100) = 2.
The calculator has a single memory register. MC clears it to 0. MR recalls the stored value. M+ adds the current display value to memory. M− subtracts the current display value from memory. The memory indicator shows the stored value when it is non-zero.
