Finding the roots of a function
WebA value is said to be a root of a polynomial if . The largest exponent of appearing in is called the degree of . If has degree , then it is well known that there are roots, once one takes into account multiplicity. To understand what is meant by multiplicity, take, for example, . This polynomial is considered to have two roots, both equal to 3. Web2 days ago · Method 1: Using Math.Pow () Function. The easiest way to find the cube root of a specified number is to use the math.Pow () function. We can use the math.Pow () function to calculate the cube root of a number by raising the number to the power of 1/3. The following code demonstrates this method −.
