Webb20 feb. 2024 · cos (2x) has a lot of equivalent ways it can be written, but a convenient way for us would involve only sines since that makes the equation a lot easier to work with. One of the identities for cos 2x is cos 2x = 1 - 2 sin 2 (x). This means an equivalent way of writing our problem is: 1 - 2sin 2 x = sin (x). ira spend down calculatorWebb28 mars 2013 · 2 Answers Sorted by: 1 I think sine squared can be done with either: sin (x).*sin (x) or sin (x).^2 Share Follow answered Mar 28, 2013 at 9:30 WheretheresaWill 5,612 5 30 42 Add a comment 1 r = (sin (theta)).^2 + (cos (theta)).^2 Share Follow answered Mar 28, 2013 at 9:30 Sam Roberts 23.9k 1 40 63 Add a comment Your Answer … ira sohn conferenceWebb7 apr. 2024 · If tita is an acute angle and sin theta equal to cos theta, then show that 4 cos square theta + 6 cos square theta + 2 sin theta minus 1 equal to 7.
