How can you tell how much battery is left in a TI-84 calculator?

You can remove the batteries and test their voltages individually. Looking at the weakest one, 1.50 or more volts is good and will have a long life. 1.0 volts or less is almost dead. Sometimes you can tell the battery is weak by the contrast on the screen, but that's a matter of experience with that calculator.

Yes, if have a programmable TI calculator, such as the TI-84, and most of the higher ones from that point.

If you do want to text message, then you need a calculator-to-calculator cable, and a program on both that allows texting. Of course, because the calculator cable is only about a foot long, it would be slightly redundant to be texting unless instead of talking. For an examples of such a program, try this page: http://www.ticalc.org/pub/83plus/basic/programs/linking/

However, you can't actually text wirelessly.

How do you key a cube function into your TI84 calculator?

How do you find your BMI?

The easiest way is with a BMI calculator or chart. You first need to know your exact measured weight and height. You can use metric or US measurements on most charts. These are available at different sites online. Good calculators (for adults and children) are available at the US Centers for Disease Control and Prevention (CDC) website. See the related question in the related questions section for more information on finding BMI charts and calculators.

What is BMI? From the CDC:

"Body Mass Index (BMI) is a number calculated from a person's weight and height. BMI provides a reliable indicator of body fatness for most people and is used to screen for weight categories that may lead to health problems."

As an alternative, you can mathematically calculate this yourself in various ways. Here are some methods provided by Answers.com contributors:

Get your height in metres.

Divide this by your weight in kilograms.

Divide your answer by your weight again.

This will give you your BMI.

take your weight, multiply by .45 then take your height in inches and multiply it by .025 then square the result. divide the product of your weight by the product of your height and youll get a number.

ex: weight: 100 lbs height: 67 inches.

100x.45= 45 and 67x.025=1.675 1.675x1.675=2.806

45 divided by 2.806= 16.037 which rounds to a BMI of 16.

The calculation for BMI is weight in kilograms divided by height in meters squared.

kg/(Meters^2)

or you can just use a free calculator.

Use an online calculator or if not, these sums:

For Imperial

BMI = ( Weight in Pounds / ( Height in inches x Height in inches ) ) x 703

BMI = ( Weight in Kilograms / ( Height in Meters x Height in Meters ) )

BMI=weight in kilograms/(height in meters)2

How do you calculator the mortgage?

The formula for calculating your monthly mortgage payment is:

M = P * (i / (1 - (1+i)^-T))

M - is the monthly payment

P - is the principle

i - is the monthly interest

T - is the term

First convert your interest (i) to a decimal

3% interest / 100 = .03 Then divide .03 by 12 months = .0025

M = P * (0.0025 / (1 - (1+0.0025)^-T))

(1+0.0025) = 1.0025

M = P * (0.0025 / (1 - (1.0025)^-T))

Next add in your Term, in this case it is 30 years (30x12=360 months)

T=360

M = P * (0.0025 / (1 - (1.0025)^-360))

1.0025 to the -360 power. For this you need to turn the negative exponent to a positive exponent, which means fractions!

1

--------------- = 0.40703

1.0025(360)

M = P * (0.0025 / (1 -0.40703))

(1 -0.40703) = 0.59297

M = P * (0.0025 / 0.59297)

(0.0025 / 0.59297) = 0.00422

M = P * (0.00422)

P is the Principle, or the total amount that you are borrowing.

In this case P = $250,000

M= $250,000 * 0.00422

M = $1055

So the monthly payment would be $1,055

What does sin mean on a calculator?

It is an abbreviation for sine, and that word together with cosine and tangent are used in simple trigonometrical calculations about right-angled triangles. If we take the shortest side of the triangle, together with the hypotenuse (the longest side) these two sides enclose an angle. The sine of that angle tells us how long the third side is compared with the hypotenuse. Draw a triangle ABC with the right angle at A, the shortest side called AB, the hypotenuse called BC, and the remaining side CA, then if we wanted the sine of angle B we would divide the length of CA by the length of CB. If you want to find the Sine of 50 degrees on a calculator you would press buttons in this order: 50, then the sin button, and the answer would be given almost instantly in the calculator's window. That's much quicker than having to calculate for yourself.
