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.
Is the number positive if the power is negative?
It does not work that way. A negative power is simply the reciprocal. So that x-a = 1/xa The reciprocal is negative or positive according to whether the number itself is negative or positive. [And, if the number is 0, the reciprocal is not defined.]
When you get the reciprocal of and negative number will it still be negative?
Yes.
What postive number is its own reciprocal?
1 is the only positive number that is its own reciprocal. -1 is the negative number that is its own reciprocal.
How do you divide a negative number by a positive fraction?
You multiply the negative number by the reciprocal of the fraction.
Why is the reciprocal of the opposite of a nonzero number the opposite of the reciprocal of the number?
Taking the reciprocal (multiplicative inverse) does not affect the positive or negative status of an integer. So the reciprocal of a negative number is negative and the reciprocal of a positive number is positive. The reciprocals will be opposites (positive/negative) just as the original numbers were.
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.
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.
Is the number positive if the power is negative?
It does not work that way. A negative power is simply the reciprocal. So that x-a = 1/xa The reciprocal is negative or positive according to whether the number itself is negative or positive. [And, if the number is 0, the reciprocal is not defined.]
When you get the reciprocal of and negative number will it still be negative?
Yes.
What postive number is its own reciprocal?
1 is the only positive number that is its own reciprocal. -1 is the negative number that is its own reciprocal.
Negative 3 is the reciprocal so what is the opposite of negative 3?
Actually the reciprocal of any number is that number in the denominator instead of in the numerator. The reciprocal of -3 is 1 over -3.
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).
How do you divide a negative number by a positive fraction?
You multiply the negative number by the reciprocal of the fraction.
What is the reciprocal of negative one nineth?
Reciprocal is -9 reciprocal of a number is one over the number, in your case 1/-1/9 = -9. To get fraction reciprocal you turn it upside down
How do you find the reciprocal of a negative number?
A number multiplied with it's reciprocal must be one. So for example if you have -(1/2), than it's reciprocal is -2.
What is the reciprical of negative two and one quarter?
reciprocal of a negative is still a negative, and 2 and a quarter can be rewritten as 9/4. The reciprocal of this number is 4/9. Therefore, the reciprocal of -2 and a quarter is -4/9.
