Witryna19 kwi 2024 · This question is from George Simmons' Calc with Analytic Geometry. This is how I solved it, but I can't find the two points that satisfy this equation: At Point P (-2,4): y = x 2 d y d x = 2 x 2 − 1 = 2 x = Slope at P. Now, the equation for any straight line is also satisfied for the tangent:
WitrynaThe term ‘latus rectum’ refers to the conic portion and is derived from the Latin words ‘latus’ which means side and rectum which means straight.

Witryna⇒ Area of triangle = 21×[−a(2a−0)−0+1(0−6a 2)] ⇒ Area of matrix = 21×(−2a 2−6a 2) ⇒ Area of triangle = 21×(−8a 2)= 4a 2(∵The area is a positive quantity, we always take the absolute value) Thus the area of the given triangle is 4a 2. Hene the correct answer is 4a 2.

CONIC SECTIONS : A conic section, or conic is the locus of a point which moves in a plane so that the ratio of its distance from a fixed point to its perpendicular distance from a fixed straight line is a constant i.e. PS = constant = e. オデドラ降臨WitrynaLatus rectum LL' passes through the focus (a, 0). Hence the point L is (a, y 1 ). There fore, y12 = 4a (a) y12 = 4a2 Take square root on both sides. y1 = ±√ (4a2) y1 = ±2a y1 = 2a or -2a The end points of latus rectum are (a, 2a) and (a,-2a). Therefore length of the latus rectum LL' = 4a.
