Parabola - Study guides, Class notes & Summaries

Area and Similar Figures In two similar triangles, the ratio of their areas is the square of the ratio of their sides. Trigonometry Identities sin²(t) + cos²(t) = 1 Functional Definition, Notation, and Interpretation In mathematics, a function is a relation between a set of inputs and a set of permissible outputs with the property that each input is related to exactly one output. Given f(x) = x² + 2x - 1, find f(2). f(2) = (2)² +2(2) - 1 = 4 + 4 - 1 = 7 Circles and O...

by looking at the vertices and co-vertices how do you know if it is vertical or horizontal? -if the vertices are on the x-axis, it is horizontal, if the vertices are on the y-axis, it is vertical -remember horizontal goes with "x" and vertical gets with "y" -your vertices always go on your major axis and the co-vertices on the minor axis how do u write the equation of an ellipse? x2/a2 + y2/b2 00:02 01:28 what should you look out for if she's talking about the he...

Equation of a Circle (x-h)^2 + (y-k)^2 = r^2 distance formula d = square root of (x-h)2 + (y-k)^2 - used to find the radius a.k.a. the distance from the center of a circle from a point on the circle. Center of a Circle (h,k) The center of a circle is equidistant from every point on the circle Standard Equation of a Parabola symmetrical over y axis (x-h)^2=4p(y-k) symmetrical over x axis (y-k)^2=4p(x-h) Directrix & Focus every point on a parbola is the same d...
