i have function, y = 50sin(x/50) + 100. want draw curve function, without additional info graph plotters, need wave on screen. x should correspond x parameter of screen , y y parameter of screen. here code of current view. public class sinusoid extends view { paint paint = new paint(); public sinusoid(context context) { super(context); paint.setcolor(color.red); } @override public void ondraw(canvas canvas) { //todo draw line using myfunction } private double myfunction(double x){ return 50 * math.sin(x / 50) + 100; } } now question is, should fill in todo? please help, documentation or example useful. thanks in advance. the idea have this: @override public void ondraw(canvas canvas) { (int x=0; x<canvas.getwidth();x++) { canvas.drawpoint(x,(float) myfunction(x),mpaint); } } but you'll need adjust value of function given canvas height.

unfortunately haven't found official resource on this. is allowed use ternary operator this, shorten , if/else statement: (isset($somevar) ? $this->setmyvar('something') : $this->setmyvar('something else')); in php documentation, ternary operator explained example: $action = (empty($_post['action'])) ? 'standard' : $_post['action']; this makes me believe use case might work, not valid because setter function not return anything. yes, can. php doc : [...] ternary operator expression, , [...] doesn't evaluate variable, result of expression. that quoted, although ternary used assigning values, can use suggested because function call expression appropriate function evaluated (and therefore executed). if setter function return value, not assigned , therefore lost. however, since said setter doesn't return anything, whole ternary operator evaluate nothing , return nothing. that's fine. if more...

i had custom 404 error redirect page working fine through htaccess. however, after adding new code htaccess, stopped working. what's causing conflict , how can fix it? edit: i've tried putting errordocument line @ top of page , still doesn't work. htaccess code: rewriteengine on #removes www rewritecond %{http_host} ^www\.(.+)$ [nc] rewriterule . http://%1%{request_uri} [r=301,l] #redirects extensionless php urls rewritecond %{the_request} ^[a-z]{3,9}\ /([^&\ ]+).php rewriterule .* /%1?
