In fact, this is a special case, and you use a different equation, not "y=", but instead you use "x= " Like this x = 15 Every point on the line has x coordinate 15, that is why its equation is x Equation = The equation = produces a graph where the curve and line intersect at (1, 1) The curve becomes asymptotic to 0, as opposed to 1;Answer and Explanation 1 Consider the given equation x = y3−6y2 9 x = y 3 − 6 y 2 9 at the given point (4,1) ( 4, 1) Implicitly differentiate the function to obtain dy dx d y d x Then
In mathematics, the binomial coefficients are the positive integers that occur as coefficients in the binomial theoremCommonly, a binomial coefficient is indexed by a pair of integers n ≥ k ≥ 0 and is written () It is the coefficient of the x k term in the polynomial expansion of the binomial power (1 x) n, and is given by the formula =!!()!For example, the fourth power of 1 x isThe solution proceeds in two steps First, the cubic equation is "depressed";This means an equation in x and y whose solution set is a line in the (x,y) plane The most popular form in algebra is the "slopeintercept" form y = mx b This in effect uses x as a parameter and writes y as a function of x y = f(x) = mxb When x = 0, y = b and the point (0,b) is the intersection of the line with the yaxis
