Correct.
if it didn't equal zero then what else would it equal
A scalene triangle has zero equal sides.
When the numerator of any expression or fraction is zero then the result is zero because zero divided by any number is always equal to zero.
Zero is refered to as the additive identity element in this situation.
Zero is equal to zero
It isn't clear what forces you are talking about. It also depends what the exact situation is.
Any number to the power zero is equal to 1 - except zero to the power zero, which is undefined. So, if x is not equal to zero, the answer is 1.Any number to the power zero is equal to 1 - except zero to the power zero, which is undefined. So, if x is not equal to zero, the answer is 1.Any number to the power zero is equal to 1 - except zero to the power zero, which is undefined. So, if x is not equal to zero, the answer is 1.Any number to the power zero is equal to 1 - except zero to the power zero, which is undefined. So, if x is not equal to zero, the answer is 1.
Any number multiplied by zero is equal to zero, including zero. Therefore, zero times zero is equal to zero. 0 x 0 = 0
How can a class frequency be equal to zero?
Yes most of them do equal zero.
A polynomial is identically equal to zero if and only if all of its coefficients are equal to zero. eg. The power series on the left is identically equal to zero, consequently all of its coefficients are equal to 0:
Correct.
if it didn't equal zero then what else would it equal
No, zero divided by four is not equal to four. It's actually equal to zero. In fact zero divided by any number is equal to zero, except for zero divided by zero because you can't divide by zero.
A scalene triangle has zero equal sides.
Zero minus zero equals zero.
