To one decimal place, the measure of angle A is 66.8¡, the measure of angle B is
23.2¡, and the length of the hypotenuse is 7.6 metres.
Hyperbolics

Pressing one of these multi-tap keys repeatedly lets you access the corresponding
hyperbolic or inverse hyperbolic function. Angle modes do not affect hyperbolic
calculations.

Logarithm and Exponential Functions
D C (multi-tap keys)
D pastes the natural logarithm, ln, of a number to the base e. The argument of the
function is ln(value).
e ≈ 2.718281828459 for calculations.
e ≈ 2.718281828 for display in Float mode.
D D pastes the common logarithm, log
10
, of a number. The argument of the
function is log(value).
D D D pastes the logBASE function as a MathPrint™ template. When
needed, the arguments in classic entry are logBASE(value,base).
C pastes e to the power function.
