What is the negative reciprocal of -3?
The reciprocal of a number is 1 divide by that number - the reciprocal of -3 is 1/(-3), or -1/3. So, the negative reciprocal of -3 would be 1/3 (without the minus sign).
What is the negative reciprocal of a slope?
The negative reciprocal of any gradient gives the gradient of the line perpendicular to it. If you had a line of gradient 2, the negative reciprocal would be -1/2 Just change the sign on the number and flip the number/fraction to get the negative reciprocal.
Why will sin and cosecant have the same sign?
The cosecant is the reciprocal of the sine function. Now, the reciprocal of a positive number is positive, and the reciprocal of a negative number is negative.
Why is a negative times a positive a negative?
Think of it like this:The product of a negative number times a number (call it B), will be the opposite sign of the sign of number B.The product of a positive number times a number B, will have the same sign as the sign of number B.
Does the number of positive factors affect the sign of a product?
No, only the number of negative factors affect its sign.
When a product of integers an odd number of negative factors then the sign of the product is?
negative
What is the sign of the product of an even number of negative factors?
The product will be positive in this case.
How can you determine the sign of the product when multiplying two or more integers?
If there are an odd number of numbers with a negative sign then the sign of the product is negative. Otherwise it is positive.
Does the number of positive factors affect the sign of the product?
No. Any number of positive factors will lead to a positive product.
How can you find the sign of the product two or more rational numbers?
Count the number of negative numbers. If this is an even number, the sign is + and if it is odd, the sign is -.
What is the reciprocal of 110?
In math a reciprocal is the number you multiply a given number by to get 1. The easiest way is to put the given number under 1 in a fraction as the denominator. Hence the reciprocal of 4 is 1/4 or 0.25, the recprocal of (x2+2xy+y2) is 1/(x2+2xy+y2) In this case the reciprocal is 1/(-110) or ... after a bit of hocus pocus with the sign ... -1/110
How do you find a reciprocal of a number with an exponent?
You change the sign of the exponent. For example, the reciprocal of 2 to the power 8 is 2 to the power -8. Alternately, you can change the whole expression to the denominator. In this case, the reciprocal of 2 to the power 8 is 1 divided by (2 to the power 8).
