Scientific Calculator Guide
This scientific calculator supports all standard mathematical functions including trigonometry, logarithms, powers, roots, factorials, and mathematical constants. Switch between Degrees and Radians for angle calculations.
Available Functions
sin, cos, tan
Trigonometric functions (press 2nd for inverse)
asin, acos, atan
Inverse trig — press 2nd then sin/cos/tan
ln / eˣ
Natural log and e to the power x
log / 10ˣ
Base-10 log and 10 to the power x
√x / x²
Square root and squaring (press 2nd)
xʸ
Raise x to any power y
n!
Factorial of n (e.g. 5! = 120)
|x|
Absolute value of x
π, e
Mathematical constants (press 2nd for e)
M+, MR, MC
Memory store, recall and clear
Frequently Asked Questions
When should I use Radians vs Degrees?
Use Degrees for everyday geometry and navigation (a right angle is 90°). Use Radians for calculus, physics, and programming (a right angle is π/2 ≈ 1.5708). Press the DEG/RAD button to switch modes. The current mode is shown in the top bar.
How do I calculate powers and roots?
For x²: press 2nd then √x. For xʸ: enter the base, press xʸ, enter the exponent, press =. For square roots: press √x then the number. For cube root: enter 3, press 2nd + xʸ (ʸ√x), enter the number.
What is the difference between ln and log?
ln is the natural logarithm (base e ≈ 2.71828). log is the common logarithm (base 10). ln is used in calculus, growth/decay problems, and natural phenomena. log is used in engineering, pH calculations, and the Richter scale.
How does the memory function work?
M+ adds the current result to memory. MR recalls the stored memory value into the display. MC clears the memory to zero. The memory value is shown in the top bar. Memory persists between calculations until you clear it.
