|
| |
This calculation device (the PolyTrig Calculator) carries out over
30 trigonometric calculations simultaneously, when the user enters numbers
for the height and base of a right triangle. The Calculator
has five sections, and many formulas in the conventional and spreadsheet
formats. |
|
| |
Simple
Three-Step Instructions: 1) Delete
the numbers in the two white Input boxes below. (To enter or delete
numbers, you must first left click with the mouse on the relevant, white
input box.) |
|
| |
2) Enter the height of your right triangle in
Input box A, and the length of the base in Input box B. |
|
| |
3) For calculated results; left click with the
mouse on the yellow background, or on the calculation button. Scroll down
to view results. (This page is about 6 computer screens from
top to bottom.) |
|
| |
This is Input Box
A, which is for the height |
This is Input Box
B, which is for the length |
|
| |
of the triangle. (Altitude or
Opposite side) |
of the base of the triangle. (Adjacent
Side) |
|
| |
A= |
|
B = |

Section 1) Calculations without
the Trigonometric Functions |
|
|
A=The height of the triangle = |
|
|
| |
|
|
Area of Triangle = |
|
|
| |
This is the height triangle. It is also the altitude or
opposite side of the triangle. |
 |
|
Spreadsheet formula for the above =A*B/2 |
|
| |
|
H = Hypotenuse = |
|
|
| |
|
|
Spreadsheet formula for above
=((A^2)+(B^2))^(0.5) |
|
| |
The dimensions of this right triangle
are used for all the calculations performed by the PolyTrig
Calculator. This includes, height, length of base and
hypotenuse, and the size of angles a and b |
|

|
| |
|
Perimeter = |
|
|
| |
|
|
Spreadsheet formula for the above = A+B+H |
|

|
B = Base (Adjacent
Side) = |

Angle a, radians = |
|
Angleb Radians = |
|
|
| |
Spreadsheet formula for the above =ATAN(A/B) |
Spreadsheet formula for the above =ATAN(A/B) |
|
|
Angle a Degrees = |
|
Angle b Degrees = |
|
|
| |
Spreadsheet formula for above
=DEGREES(ATAN(A/B)) |
Spreadsheet formula for above =
DEGREES(ATAN(B/A)) |
|
| |
|
The rounding mechanism, presented below, is NOT
for the above calculations. |
|
|
| |
All of the FOLLOWING calculated results are
rounded to |
|
decimal places. You can
|
|
| |
change this, by deleting the above number (in
blue type), and entering the number of decimal |
|
| |
places you prefer. If
you enter a number that is excessively large you might get rounding
errors. |
