Can anyone help with paramaterization of conics?
Im struggling to wrap my head around an example. It considers the conic x2+y2z2=0 then proceeds:
Take A=[1,0,1] and the line P(U) defined by x=0. Note that this conic and the point and line are defined over any field since the coefficients are 0 or 1. A point XP(U) is of the form X=[0,1,t] or [0, 0, 1] and the map α is

α ( [ 0 , 1 , t ] ) = [ B ( ( 0 , 1 , t ) , ( 0 , 1 , t ) ) ( 1 , 0 , 1 ) 2 B ( ( 1 , 0 , 1 ) , ( 0 , 1 , t ) ) ( 0 , 1 , t ) ] = [ 1 t 2 , 2 t , 1 + t 2 ]  or  α ( [ 0 , 0 , 1 ] ) = [ 1 , 0 , 1 ] .


How do I evaluate B(v,v) or B(v,v)(a,b,c) like they have to go from the first line to the second?

Sally has caught covid but doesn’t know it yet. She is testing herself with rapid antigen kits which have an 80% probability of returning a positive result for an infected person. For the purpose of this question you can assume that the results of repeated tests are independent. 

a) If sally uses 3 test kits what is the probability that at least one will return a positive result? 

b) In 3 tests, what is the expected number of positive results?

c) Sally has gotten her hands on more effective tests, these ones have a 90% probability of returning a positive result for an infected person. If she tested herself
twice with the new tests, how many positive results would she expect to see?

Elliptic integrals The length of the ellipse

x=acost,y=bsint,0≤t≤2πx=acost, y=bsint, 0t2π

turns out to be

=4a∫π/201−e2cos2t√dt=4a0π/21e2cos2tdt

where ee is the ellipse's eccentricity. The integral in this formula, called an elliptic integral, is non elementary except when e=0e=0 or 1 a. Use the Trapezoidal Rule with n=10n=10 to estimate the length of the ellipse when a=1a=1 and e=1/2e=1/2 . b. Use the fact that the absolute value of the second derivative of f(t)=1−e2cos2t√f(t)=1e2cos2t is less than 1 to find an upper bound for the error in the estimate you obtained in part (a).

  1. A strawberry jam company regularly receives large shipments of strawberries. For each shipment that is received, a supervisor takes a random sample of 500 strawberries to see what percent of the sample is bruised and performs a significance test. If the sample shows convincing evidence that more than 10%, percent of the entire shipment of strawberries is bruised, then they will request a new shipment of strawberries.

 

Let p represent the proportion of the strawberries in a shipment that are bruised.
