Scientific Calculator

Basic Operation

1. Enter a number in the input field
2. Click on any function button to apply that function to your number
3. The result will appear immediately below the input
4. The result automatically becomes the new input for chain calculations

Using Constants

Click on any constant button (π, e, φ, √2, √3) to insert that value into the input field.

Memory Functions

• MS (Memory Store): Store the current input value in memory
• MR (Memory Recall): Recall the stored memory value
• M+ (Memory Add): Add current value to memory
• M- (Memory Subtract): Subtract current value from memory
• MC (Memory Clear): Clear the memory

Function Categories

• Trigonometry: sin, cos, tan and their inverse functions (working in degrees)
• Logarithm: Common log (base 10) and natural log (base e)
• Power: Square, cube, roots, and exponential functions
• Other: Factorial, absolute value, rounding functions

A scientific calculator is an essential tool for advanced mathematics, engineering, physics, and scientific computations. Unlike basic calculators, scientific calculators provide access to mathematical functions beyond simple arithmetic.

Trigonometric Functions

Trigonometric functions relate angles to ratios of sides in right triangles. They're fundamental in physics, engineering, and mathematics:

• sin (sine): Opposite side / Hypotenuse
• cos (cosine): Adjacent side / Hypotenuse
• tan (tangent): Opposite side / Adjacent side
• Inverse functions (sin⁻¹, cos⁻¹, tan⁻¹): Find angles from ratios

Logarithmic Functions

Logarithms are the inverse of exponential functions, useful for solving exponential equations and working with very large or small numbers:

• log (common logarithm): Base 10 logarithm, often used in scientific notation
• ln (natural logarithm): Base e logarithm, fundamental in calculus and natural sciences

Important Mathematical Constants

• π (Pi): Ratio of circle's circumference to diameter ≈ 3.14159
• e (Euler's number): Base of natural logarithm ≈ 2.71828
• φ (Golden ratio): Special proportion found in nature ≈ 1.61803

Key Mathematical Formulas

• •Use memory functions (MS, MR, M+, M-) to store intermediate results in complex calculations
• •Chain operations by using the result of one calculation as input for the next
• •Remember that trigonometric functions work in degrees, not radians
• •For very small or large numbers, scientific notation (e.g., 1.23e-5) is used automatically
• •Inverse trig functions (sin⁻¹, cos⁻¹, tan⁻¹) require input values between -1 and 1
• •The factorial function only works with non-negative integers
• •Use the constant buttons for precise values of π, e, and other mathematical constants
• •The history feature shows your last 10 calculations for reference
