This is the Maclaurin series for cos x. It is quite amazing that a power series can represent a trigonometry function in this way. The cos x series contains even powers and factorials, and the sin x series contains odd powers and factorials. Also, notice that each successive term alternates its sign.

0, (2pi)/3, (4pi)/3, 2pi Use the identity: cos 2x = 2cos^2 x - 1. The given equation transforms to: 2cos^2 x - cos x - 1 = 0. Solve this quadratic equation for cos x. Since a + b + c = 0, use shortcut. There are 2real roots: cos x = 1 and cos x = c/a = - 1/2. a. cos x = 1 --> x = 0 or x = 2pi b. cos x = - 1/2 ---> x = +- (2pi)/3 The co-terminal to arc - (2pi)/3 --> arc (4pi)/3 Answers for (0

Minnesregel: För att lättare komma ihåg tecknen kan vi använda samma minnesregel som vi har använt då vi har deriverat de trigonometriska funktionerna men då man söker en primitiv funktion måste man gå motsols (moturs) i cirkeln. Graph of cos(x) is symmetric about the y axis. You get the same values as output for every pair of positive and negative input x. Thus, cos(x) is an even function.

The cos x series contains even powers and factorials, and the sin x series contains odd powers and factorials. Also, notice that each successive term alternates its sign. In plain English, it just means (cos x)/x goes to infinity as x goes to 0 +.
