Svara i grader. cos(2x) = cos2 x – sind x = 2 cos2 x – 1=1 - 2 sin2 x sin2r -1- cos 2x. 2 cos x = cos 2x – 1. 2 sin(2x ) = 2 sin x Cos X. COS X tan(2x) = 2 tan x. 1 – tan2 x. • sin, cos Om r(u,v) är en rationell funktion i u och v, så kan man alltid överföra en integral av formen ∫ r(sin x,cos x) dx på en integral av en rationell funktion i t med hjälp Förenkla uttrycket cos x sin 2x − sin x cos 2x.

My second attempt at an actual in class video. This one was way harder to edit and I'm not sure how I feel about it.For more math shorts go to www.MathByFive

sin^2 x + 2 sin x cos x + cos^2 x. You can combine the first and last terms using a trigonometric identity-- sin^2 x + cos^2 x = 1. 1 + 2 sin x cos x. Another identity is that 2 sin x cos x = sin 2x, so you end up with. 1 + sin 2x Cos^2 + Sin^2 = 1^2 = 1 StupidLemonEater commented July 25, 2020 Here’s another proof: if you have a right triangle with side lengths a, b, and c (where c is the hypotenuse) then the sine of the angle opposite side a (let’s call it x) is equal to a/c.
