A powerful online scientific calculator with advanced mathematical functions including trigonometry, logarithms, exponents, and more. Perfect for students, engineers, and professionals.
15 + 25 × 3 = 90
5² = 25√16 = 42⁸ = 256
sin(30) = 0.5cos(60) = 0.5tan(45) = 1
log(100) = 2ln(e) = 110³ = 1000
5! = 12010! = 3,628,800
6.022 EXP 23= 6.022 × 10²³
DEG (Degrees): Most common angle measurement. Full circle = 360°. Use for everyday calculations.
RAD (Radians): Mathematical standard. Full circle = 2π radians. Used in calculus and advanced mathematics.
GRAD (Gradians): Full circle = 400 grads. Rarely used, mainly in some European surveying.
For percentage of a number: 50 × 20% = 10
For percentage increase: 100 + 20% = 120
For percentage decrease: 100 - 20% = 80
log is the logarithm with base 10 (common logarithm). Example: log(100) = 2 because 10² = 100
ln is the natural logarithm with base e (≈2.718). Example: ln(e) = 1 because e¹ = e
MS (Memory Store): Saves the current displayed value to memory
MR (Memory Recall): Displays the value stored in memory
M+ (Memory Add): Adds current value to what's in memory
M- (Memory Subtract): Subtracts current value from memory
MC (Memory Clear): Clears the memory (sets to 0)
EXP is used for scientific notation to represent very large or very small numbers. For example:
6.022 EXP 23 represents 6.022 × 10²³ (Avogadro's number)
1.6 EXP -19 represents 1.6 × 10⁻¹⁹ (electron charge in coulombs)
Inverse trigonometric functions (sin⁻¹, cos⁻¹, tan⁻¹) are also called arc functions.
Example: If sin(30°) = 0.5, then sin⁻¹(0.5) = 30°
These functions help find the angle when you know the ratio.
