sin 2 ⁡ ( x ) + cos 2 ⁡ ( x ) = 1 {\displaystyle \sin ^ {2} (x)+\cos ^ {2} (x)=1} sin ⁡ ( x ) = ± 1 − cos 2 ⁡ ( x ) {\displaystyle \sin (x)=\pm {\sqrt {1-\cos ^ {2} (x)}}} cos ⁡ ( x ) = ± 1 − sin 2 ⁡ ( x ) {\displaystyle \cos (x)=\pm {\sqrt {1-\sin ^ {2} (x)}}} The answer is = 1 2 sin 6 x + 6 x + C Explanation: We use cos 2 x = 2 cos 2 x − 1 Adapting this cos 6 x = 2 cos 2 (3 x) − 1 The trigonometric functions cos and sin are defined, respectively, as the x- and y-coordinate values of point A. That is, cos ⁡ θ = x A {\displaystyle \cos \theta =x_{\mathrm {A} }\quad } and sin ⁡ θ = y A . {\displaystyle \quad \sin \theta =y_{\mathrm {A} }.} Free math problem solver answers your algebra, geometry, trigonometry, calculus, and statistics homework questions with step-by-step explanations, just like a math tutor.

Ja, det är två helt olika saker.

cos2x skulle jag hellre skriva som cos (2x), alltså Cosinus för dubbla vinkeln. Om x är pi/6 radianer (samma som 30 grader) 2*cos (pi/3) = 2 * sqrt (3)/2 = sqrt (3) cos (2*pi/6) = cos (pi/3) = 1/2.
