SOURCE: I want to complete normal calculations. the

OK,do not worry. Press [2nd][MODE] to access tghe (SETUP) options. Then press 2 to select [2:LineIO]. from now on all your results will be displayed as decimal numbers. Do not pay attention to the D for degrees, if you are not doing angle calculations or trigonometry.

Another point. Since you only want to balance the checkbook, all your numbers have at most 2 decimal digits and it might be less tiresome for you if you configure your calculator to display just 2 figures after the decimal mark.

To do that

  1. Press [2nd][MODE].
  2. Enter 6 to select [6:FIX].
  3. Then enter 2.

How to calculate cubic feet?


Multiply 21 inches by 14 inches by 10 inches to get 2940 cubic inches. There are 12 inches in a foot, so there are 12^3=1728 cubic inches in a cubic foot. Divide 2940 cubic inches by 1728 cubic inches per cubic foot to get about 1.7 cubic feet.

Alternatively, first convert all measurements to feet. 21 inches is 1 3/4 feet, 14 inches is 1 1/6 feet, 10 inches is 5/6 feet. Multiply them together to get 245/144 cubic feet, which again is about 1.7 cubic feet.

It's always nice when doing a problem two different ways gives the same answer.

I measured a freezer in inches which Are 20 30 20 Please calculate in cibic feet


20 inches times 30 inches times 20 inches is 12,000 cubic inches. There are 12 inches in a foot, so one foot is 12^3 or 1728 cubic feet. 12,000 cubic inches divided by 1728 cubic inches per cubic foot is about 6.9 cubic feet.

Sharp el-501w figure degree on rise run seven inch rise tweve inch run = ? degree


If you have learned about the trigonometric ratios (sine, cosine and tangent) you can use the tangent of the angle.
Let your run be to the right ( along the positive x-axis) and the rise be upwards along the positive y-axis. The tangent of the angle is
tan (theta)=rise/run=7.5/12
If the calculator is set with angle unit in degrees, the angle is obtained as the arc tangent of the (rise/run) value.

theta= arctan(7.5/12)=32.00538321 or about 32 degrees.

The arctan is the inverse of tan. To access it on the calculator press [2nd F][tan]
Depending on the calculator (sorry I do not have your model under my eyes)
Press [2nd F][tan] ( 7.5/12) [=]
or
7.5/12 = then [2nd F][tan] [ALPHA][Ans] [=]

What size npt thread is the adaptor


Common American National Standard Pipe Taper Threads
  • NPT - National Pipe Thread Taper
  • FPT - female (internal) National Pipe Taper threads
  • MPT - male (external) National Pipe Taper threads
  • NPTF - Dryseal American National Standard Taper Pipe Thread (ANSI B1.20.3)
For NPT threads a sealant compound or Teflon tape must be used for a leak-free seal. For NPTF no sealant is needed for a sealing.
Characteristics of NPT (also known as ANSI/ASME B1.20.1 Pipe Threads, General Purpose):
  • tapered thread 1o 47'
  • truncation of roots and crests are flat
  • 60o thread angle
  • pitch is measured in threads per inch
Note! Pipe sizes do not refer to any physical dimensions. The outside diameter of a pipe or fitting must be measured and compared to a table for size identification. A 3/4" NPT pipe thread has an outside diameter - OD - of 1.050 inches.
Each thread size has a defined number of threads per inch - TPI, or pitch. The 3/4" NPT pipe thread has 14 threads per inch. Both the TPI and OD of the thread are required for positive identification of thread size because more than one size have the same TPI.

NPT threads are not interchangeable with NPS - National Pipe Straight - threads.
NPT threads may look similar to ISO 7/1 threads. However, ISO and NPT threads should not be mixed. ISO threads have 55o taper angle versus 60o for NPT. The NPT root and crest configurations are also different from ISO. For ISO threads pitch is usually measured in millimeters (may be expressed in Inch). The pitch are different.

I can't seem to be able to figure out how to find the cosine tangent or sine of an angle...Help?


Unlike traditional calculators, the FX9750G uses textbook order to call functions. For example, to calculate the sine of 45°, you key in (angle argument unit set to degrees assumed):

[sin] 45 [EXE]

Cosine and tangent are analogous. Argument format can be degrees, radians or grad. You can set up the angle argument unit by keying in:

[SHIFT] [SETUP] [v] [v] [v] [v] and then
  • [F1] (Deg) [EXIT] for degrees (1 full circle = 360°),
  • [F2] (Rad) [EXIT] for radians (1 full circle = 2pi),
  • [F3] (Grad) [EXIT] for grad (1 full circle = 400 gon).

For get the life of me I can not figure out how to get the degree of a cos angle. For ex. cos theta = 6.5/25 = 0.26 now how do I find the degree? Shouldnt it be 2nd key + cos + 0.26 + enter? the answer...


When using trigonometric functions (cos, sin, tan) and their inverses (arccos, arcsin, arctan) one must be aware that the result will depend on the default angle unit : radian, degree, or grad.

Apparently you are working with the degree as the angle unit, so you must configure the calculator for that unit. (See screen capture below)
Press [SHIFT][MODE] [3:Deg]
