trigonometry - how to implement trigonometric expressions using a programming language? - 


*expression:      -(sqrt((a0+a1 cos wt +a2 cos 2wt )^2 +(a1sin wt +a2 sin 2wt)^2     - ـــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــ     - sqrt ((1+b1cos wt+b2 cos 2wt)^2 +(b1 sin wt+b2 sin2 wt )^2   *variables:     - a0=.2     - a1=1.2     - a2=a0=.2     - b1=1.6     - b2=.8     - f=32khz

*question:

  • i supposed use programming language (not matlab) implement exp , observe o/p signal .... how can , language if possible?

in c#, can use system.math, believe has every function need:

  • abs
  • exp
  • sin
  • cos
  • sqrt
  • ... lot of other methods ...

data type depends on accuarcy need, can use decimal data type.

example:

decimal a0 = 0.2; decimal a1 = 1.2;  decimal result = math.cos(a0) * a1 - math.sqrt(a1);

basically, programming languages have sort of math library, should contain functions.

c# - Send Image in Json : 400 Bad request -

from android trying send image class of data, iis webservice. (c#) the problem 400 bad request . the image being encoded base64 . , placed json rest of class elements. my guess base64 not valid inside json. server not understand it. if set string "" , post accepted fine. so question is, how make base64 valid within json array? ( tried url.encode no success). or how should send image android webservice? gson gson = new gson(); string json = gson.tojson(record); // record has param { string base64photo } how big image? i'm pretty sure surpassing iis json size limit (default 4 mb). check http://geekswithblogs.net/frankw/archive/2008/08/05/how-to-configure-maxjsonlength-in-asp.net-ajax-applications.aspx or http://www.webtrenches.com/post.cfm/iis7-file-upload-size-limits good luck!
