Solution: The travel time is given by the following formula: 
 
  t =       437    x      tan (63 degrees)        
  135 x ASINH (tan (63 degrees) ) 
 
 Assuming the 35s is in Radians mode, change it to Degrees mode to calculate the tangent value.

hp calculators - 2 - HP 35s  Solving for roots - Version 1.0 
Roots of an equation 
 
The roots of an equation are values of X where the value of Y is equal to zero. For example, the equation Y = X – 2 has 
a real root at the value +2. The equation Y = X2 – 9 has real roots at the values of + 3 and – 3. Not every equation has 
roots that are real numbers. For example, the equation Y = X2 + 4 has no real roots, meaning there are no real values for 
X that...

Numbers in different bases 
 
Most numbers we work with day-to-day are in base 10. There are applications within the computer world that require the 
use of numbers in other bases. The number 24 in base 10 can be translated into base 16 by the following procedure. 
Just as each digit’s location in base 10 can be thought of as a power of ten (the ones’ place, the tens’...
