π2. Answer. C 3. x=–5pi/24+npi, x=11pi/24+npi 5. x=–pi/3+2npi, x=–2pi/3+2npi.

For math, science, nutrition, history To calculate cosine online of `pi/6`, enter cos(`pi/6`), after calculation, the result `sqrt(3)/2` is returned. Note that the cosine function is able to recognize some special angles and make the calculations with special associated values in exact form. Calculate cos(2π/3) Determine quadrant: Since our angle is greater than π/2 and less than or equal to π radians, it is located in Quadrant II In the second quadrant, the values for sin are positive only. Determine angle type: 120 is an obtuse angle since it is greater than 90° cos(2π/3) = -1/2 Here is the answer for the question – cos (2pi/3). You’ll find the correct answer below cos (2pi/3) The Correct Answer is -0.5 Reason Explained -0.5 is correct for cos (2pi/3) Answerout (2pi)/3 is equal to 120 degrees, because (2pi)/3*(180/pi) equals 2*60, which equals 120.

Och jag räknar: eller x+pi/4=2pi/3 +n*2pi t.ex. så är ju sin(30 grader) = 1/2 och 30 grader är ju pi/6 och inte pi/3. Svara. synd ((2pi) / 3) Kos pi Tan ((2pi) / 3) Spjälsäng ((5pi) / 6) = 1/2 * -1 * -1 / sqrt3 * -1 / sqrt3 = -1 / 6 cos pi = cos180 = -1 sin ((2pi) / 3) = sin 120 = sin (90 +30) = sin Så vi hittar maximeraren till (5-a)²a³ (obs att konstanten pi/3 är bortdelad i detta steget) Borde det inte bli att y = 6*2pi/30 cos(2pi/30 x)?. 3.

cos 2/3 pi ile to jest. potrzevbuje konkretna liczbe bo to jest mi potrzebne do zadnia zwyklego liczenia nie do rownan tryg I dont know how to type cos^2(x)- sin^2(x) into matlab. I think it is cos(x).^2 - sin(x).^2. Also I know the interval is typed out [-2*pi, 2*pi} but I dont understand what the question means by saying using 100 points in the domain how to calculate the fourier transform and plot it of m(t)=cos(2*pi*9*t) 0Innovation pioneers
