Question 1

How do I use trigonometric functions?

Accepted Answer

Click the sin, cos, or tan buttons, or type them in the expression. Make sure to set the correct angle mode (Degrees or Radians) using the toggle. For example, sin(30) in degrees mode equals 0.5. Use inverse functions (sin⁻¹, cos⁻¹, tan⁻¹) for arc functions.

Question 2

What's the difference between degrees and radians?

Accepted Answer

Degrees use 360° for a full circle (common in everyday use). Radians use 2π for a full circle (common in mathematics and physics). Toggle between modes using the Degrees/Radians button. Most users prefer degrees for basic calculations.

Question 3

How do I use logarithms and exponentials?

Accepted Answer

Use 'log' for base-10 logarithm (log(100) = 2) and 'ln' for natural logarithm (ln(e) = 1). Use 'eˣ' for exponential function. For example, log(100) + ln(e) = 3. These functions are useful for scientific and engineering calculations.

Question 4

What are hyperbolic functions?

Accepted Answer

Hyperbolic functions (sinh, cosh, tanh and their inverses) are similar to trigonometric functions but for hyperbolas. Click 'Hyperbolic' to show these functions. They're used in advanced mathematics, physics, and engineering calculations.

Question 5

How do I use constants like π and e?

Accepted Answer

Click the 'Constants' menu to access mathematical constants (π, e, φ) and physical constants (c, h, NA). Click any constant to insert it into your expression. For example, 2 * π calculates 2π, and e^1 calculates Euler's number.
