Question | Answer |
---|---|
X-intercept? | y=0 |
Y-intercept? | x=0 |
Vertical Asymptote? | the limit as X approaches X sub zero of the function = + or - infinity |
Horizontal Asymptote? | the limit as X approaches + or - infinity of the function = L, graph levels off at y=L at ends. |
Oblique Asymptote? | is degree of numerator exceeds the degree of the denominator by one. divide numerator by the denominator. |
Cusp? | If: 1) f(x) is continuous at Xsubzero 2) f(x) has a vertical tangent at x=xsubzero 3) fprime(x)goes to infinity on one side and -infinity on the other. |
Newton's Method | Xn+1 = Xn - (f(Xn)/fprime(Xn)) |
For area, find delta x... | delta x = b-a/n |
inscribed means... | Under the curve, underestimation |
Circumscribed means... | over the curve, overestimation |
Redefine an index for a summation. | (top-bottom)+1 |
summation of K from K=1 to n | n(n+1)/2 |
summation of K^2 from K=1 to n | n(n+1)(2n+1)/6 |
summation of K^3 from K=1 to n | (n(n+1)/2)^2 |
steps to interpret an antiderivative as area | 1) delta x 2) points of subdivision 3) area of Kth rectangle(Ak = f(Ck)(delta x) 4)approimate total area(summation from K=1 to n) 5)Actual area (limit of approx. area) |
Riemann sum | Approx. Area = summation of f(Xk*)(delta Xk)from K=1 to n |
