Scientific calculator

Click the > or < icon on the left side of the display, double-click the display, or press [TAB] to switch between the scientific and simple calculator.

• 2nd
  [Space] Changes the trigonometric keys (sin, cos, tan, sinh, cosh and tanh)
  their inverse functions (sin-1, cos-1, tan-1, sinh-1, cosh-1, and tanh-1). It also changes ln to log2,
  and ex to 2x. Press 2nd again to return the buttons to their original functions.

• (
  [(] Opens an expression within brackets. Expressions can be nested. Clicking it allows a white ring to appear around the button to let you know that the bracketed expression is still active (until all expressions are closed by a closing bracket or equation sign).

• )
  [)] Closes the expression enclosed in brackets. The white ring around the key ( bracket) will remain until all expressions are closed using this key or after pressing the equation sign.

• %
  [%] Calculates percentages, adds markups and subtracts discounts. To calculate a percentage, use the +, -, ×, or ÷ keys to calculate it. For example, to calculate 8% of 500, enter 500 x 8% (without the equation key (=)), which returns 40. To add a markup or subtract a discount, optionally use the equation key (=). For example, to calculate the total cost of an item costing 500 with an 8% sales tax, enter 500 + 8% =, which returns 540.

• 1/x
  [{ or h, 1] Returns the inverse of the value in decimal format.

• x²
  [h, 2] Squares the value.

• x³
  [h, 3] Dice value.

• y^x
  [^ or ' or "] Click between values to increment the first value to the degree of the second value.
  For example, to calculate 34, enter 3 yx 4 =, which returns 81.

• x!
  [x] Calculates the factorial of the value (integers only).

• √
  [h, r] Calculates the square root of the value.

• ^x√y
  [r] Use values between values to calculate the root of x from y. For example, to calculate 4√81,
  enter 81 x√y 4 =, which returns 3.

• log
  [Shift+L] Returns the logarithmic base 10 of the value.

• sin
  [s] Calculates the sine of the value.

• sin^-1
  [Shift+S] Calculates the arcsine of the value. (Available when the second button is pressed.)

• cos
  [c] Calculates the cosine of the value.

• cos^-1
  [Shift+C] Calculates the arccosine of the value. (Available by pressing the second button.)

• tan
  [t] Calculates the tangent of the value.

• tan^-1
  [Shift+T] Calculates the arctangent of the value. (Available by pressing the second button.)

• ln
  [l] Calculates the natural logarithm of the value.

• log₂
  [h, l] Calculates the log base 2. (Available when the 2nd button is pressed.)

• sinh
  [h, s] Calculates the hyperbolic sine of the value.

• sinh^-1
  [h, Shift+S] Calculates the inverse hyperbolic sine of the value. (Available by pressing the second button.)

• cosh
  [h, c] Calculates the hyperbolic cosine of the value.

• cosh^-1
  [h, Shift+C] Calculates the archyperbolic cosine of the value. (Available by pressing the second button.)

• tanh
  [h, t] Computes the hyperbolic tangent of the value.

• tanh^-1
  [h, Shift+T] Calculates the archyperbolic tangent of the value. (Available by pressing the second button.)

• e^x
  [e] Press after entering a value to raise the constant "e" (2,718281828459045...) to the power of that value.

• 2^x
  [Shift+X or h, e] Calculates 2 to the power of the displayed value. For example, 10 2x = 1024. (Available by pressing the second button.)

• Rad
  [d or °] Changes the mode for expressing trigonometric functions in radians.

• Deg
  [d or °] Changes the way trigonometric functions are expressed in degrees.

• π
  [p] Enters the PI or π value (3,141592653589793...).

• EE
  [Shift+E] An operator that multiplies the currently displayed value by 10 to the power of the next value you enter.

• Rand
  [h, n or h, d] Returns a random number between 0 and 1.
