javascript - How to get a Right Triangle's points' coordination in the space? -


i have right triangle equal legs of 1 unit long rotated on 3 individual angles in space in picture below:

triangle's picture

as seen in picture, input have angles 'a' , 'b' rotates triangle in space , move orientation 1 "red triangle in picture" (the triangle still laying on z-axis), rotates on 1 of it's legs ('c' angle) , turns second orientation "the green triangle in picture".

also, right corner located on (0,0,0).

here question:

how in simple mathematics, can 2 coordination (marked in blue in picture) green triangle, in x, y , z?

i need in simple mathematics can code in javascript.

never mind.

i reviewed triangular knowledge , solved problem basic functions including sine, cosine , arctangent!

now have points in space!

css - SVG using textPath a symbol not rendering in Firefox -

using textpath within symbol doesn't render in firefox. renders fine in latest chrome , ie, when try reference symbol, svg text doesn't render in firefox (37.0.1) - first box appears empty. code below (no external dependencies), there should 2 boxes word test flowing vertically in centre of each. edit: thought issue somehow involved flexbox layout, until paul pointed out issue exists without flexbox layout. the html is: <div> <svg id="not_working" viewbox="0 0 250 1200" preserveaspectratio="xmidymid meet"> <symbol id="test_symbol1" preserveaspectratio="xmidymid meet" viewbox="0 0 250 1200"> <path id="test_symbol_path" d="m 100 1200 l 100 0" /> <text font-size="100" fill="red"> <textpath text-anchor="middle" startoffset="50%" xlink:href="#test_symbol_path...

datatable - Matlab struct computations -

i download data yahoo! finance with: data = getyahoodailydata({'msft', 'axp'},'01/01/2000', '01/01/2015', 'dd/mm/yyyy'); and data stored 1x1 struct. want create tx2 matrix of daily adjusted closing prices msft , axp, column 7 in each table in struct. how can that? or better : there way make computations directly on information/prices in struct? you can access data in struct name. vecmsftadj = data.msft.adjclose; vecaxpadj = data.axp.adjclose; % if want n x 2 matrix madjclose = [vecmsftadj, vecaxpadj]; % personnaly prefer working table tadjclose = table; tadjclose.msftadj = vecmsftadj; tadjclose.axpadj = vecaxpadj;
