1 Answer +1 vote . answered Dec 11, 2018 by And if you mean the general anti-derivative of cos(x 2), it is not an "elementary" function.That is, it cannot be written in terms of functions you normally learn (polynomials, rational functions, radicals, exponentials, logarithms, trig functions. sin(x) = sqrt(1-cos(x)^2) = tan(x)/sqrt(1+tan(x)^2) = 1/sqrt(1+cot(x)^2) cos(x) = sqrt(1- sin(x)^2) = 1/sqrt(1+tan(x)^2) = cot(x)/sqrt(1+cot(x)^2) tan(x) = sin(x Um beispielsweise eine Stammfunktion aus der Differenz der folgenden Funktionen `cos(x)-2x` online zu berechnen, ist es notwendig, stammfunktion(`cos(x)-2x;x`) einzugeben, nach der Berechnung wird das Ergebnis `sin(x)-x^2` ausgegeben. Rationale Brüche online integrieren. Statement 2: $$\cos 2x = 1 - 2\sin^2 x$$ Proof 2: We can prove that $$\cos^2(x) - \sin^2(x) = 1 - 2\sin^2(x)$$ because the left-hand side is equivalent to $$\cos(2x)$$. Add $$2\sin^2(x)$$ to both sides of the equation: $$\cos^2(x) + \sin^2(x) = 1$$ This is obviously true.

cosx − (2cos2x −1) = 0. −1[cosx −2cos2x +1] = 0. 2cos2x − cosx − 1 = 0. (2cosx + 1)(cosx −1) = 0. cosx = − 1 2 or cosx = 1. x = cos−1( − 1 2) or x = cos−11. x = ± 2π 3 +2πn or x = 0 + 2πn. S = { ± 2π 3 +2πn,0 + 2πn} Answer link.

CORRECTION at the end of simplification :There should be another 2 inside the bracket.The end result will be 4 cosx cos5x/2 cosx/2 = 0.The answer is correct
