This is how they will treat the estimates
Take your time and do them well

Parametric equations
Varying a single parameter t , you are able to generate circle

Parametric equations
Varying only the parameter t ,
you are able to generate a parabola

Steps to parametric
1. Find out the parameters of project2.Find the weights for the parameters3.Find out the frequency of parameters4.Find out the aggregating equation 5.Compute the estimate

Assignment on Parametric Estimates
Estimate the Web 2.0 project : What Tweet means
Explanation : The most notable persons on earth viz, Obama, Modi, Aamir Khan or Deepika Padukone are tweeting everyday. Often there is a difference between what they tweet and what they mean. Example See a Narendra Modi tweet and possible WhatTweetMeans
For this Web 2. O twitter app . The user should be • Create account using twitter• Should be able to see his timeline on twitter• Should be able to start a thread of new “ WhatTweetMeans “ ie interpret
any tweet in text/image/gif and post it • Other people should be able to vote the interpretation up and down• The WhatTweetMeans – should be viewable by # of vote ups or time
currency of the posting.• People should be able to share the thread of what he means • They should be able to report abusive WhatItmeans.
Estimate the project using parametric estimates.
