Math is very useful. You may not realize it but you are always using math. From counting how many eggs to cook or paying for something you'll always need it. I personally don't love math but i know it will be extremely useful in my future.

Interest and percent I know. Proportions are useful for finding that.

-My teacher likes for us to use math terms, such as reciprocal, in class.

yes, math is useful. But you probably won't need higher then 1st year calc

Flip is the technical term for a reciprocal. (The reciprocal of 3/4 is 4/3)

Math sucks c:

The reciprocal of a number is: 1 divided by the number. Example: the reciprocal of 2 is 1/2 and 5 is 1/5..

The reciprocal is the "multiplicative inverse". This means 1 divided by the number. The reciprocal of 2 is 1/2, the reciprocal of 5 is 1/5, etc.

A reciprocal is when you take the second fraction in a division problem and flip it Then change the sign to multiply. THIS ONLY WORKS WHEN YOU ARE DIVIDING FRACTIONS!

1/a is the reciprocal of a

FormulasMath is useful in science because you might want to make a graph, or you might have to measure things, or add amounts, and so much more. Math is really useful if you are a scientist.

Reciprocal in math means to flip a number. 2x can also be expressed as 2/1 (2 over 1) x. So the reciprocal of 2x is 1/2 (one over two) x.

Remainder: Remainder is what you have left after dividing a number. Reciprocal: This is the multiplicative inverse of any number(ex. the reciprocal of 5 = 1/5 and the reciprocal of 4/5 = 5/4).

if you want to do on your own look in you math book reciprocals in the index you will find fast but , depends on what kind of math book you have .

When the numbers within a fraction are reversed, this is called a reciprocal. A reciprocal is useful when dividing fractions - dividing by a fraction is the same as multiplying by its reciprocal.For example, 4 / 2/3 = 4 x 3/2 = 6.

That's how division is formally defined in advanced math.

a recipricol of a fraction is the fraction flipped over, with the numerator in the denominators place and vice versa.

Usually the same as reciprocal. The inverse of 3/4 is 4/3

Since sin(a)=opposite/hypotenuse, the reciprocal function is that function which is equal to hypotenuse/opposite. This is "cosecant", or csc(a). The reciprocal of sin(a) is csc(a). I will solve all your math problems. Check my profile for more info.

Its reciprocal is either less than 0 or greater than 1.

Negative reciprocal is something you use in math that often times help you find a perpendicular line to an equation. ex: for an equation with a slope of 5x, the recriprocal would be -1/5x. what you do is you flip flop the bottom and the top, 1/5x. That is the reciprocal alone and to make it a negative reciprocal you just simply add the negative sign.
