In elementary algebra, the binomial theorem (or binomial expansion) describes the algebraic expansion of powers of a binomialAccording to the theorem, it is possible to expand the polynomial (x y) n into a sum involving terms of the form ax b y c, where the exponents b and c are nonnegative integers with b c = n, and the coefficient a of each term is a specific positiveY=2x2 Swap sides so that all variable terms are on the left hand side 2x2=y Subtract 2 from both sides 2x=y2 Divide both sides by 2 \frac{2x}{2}=\frac{y2}{2} Dividing by 2 undoes the multiplication by 2 x=\frac{y2}{2} sin (x – y) = sin x cos y – cos x sin y sin (60° – 30°) = sin 60° cos 30° – cos 60° sin 30° sin (30°) = (√3/2) × (√3/2) (1/2) × (1/2) 1/2 = 3/4 – 1/4 1/2 = 2/4 1/2 = 1/2 Hence verified cos (x y) = cos x cos y – sin x sin y cos (60° 30°) = cos 60° cos 30° – sin 60° sin 30°

Hence, the first cos 2X formula follows, as \(\cos 2X = \cos ^{2}X – \sin ^{2}X\) And for this reason, we know this formula as double the angle formula, because we are doubling the angle Other Formulae of cos 2X \(\cos 2X = 1 – 2 \sin ^{2}X \) To derive this, we need to start from the earlier derivation As we already know that,Squaring both sides of the equation, we get the equation of the circle (x h) 2 (y k) 2 = r 2 Notice that if the circle is centered at the origin, (0, 0), then both h and k in the equation above are 0, and the equation reduces to what we got in the previous section x 2 y 2 = r 2 Example Find the equation of the circle with center (4Expected Value and Standard Dev Expected Value of a random variable is the mean of its probability distribution If P(X=x1)=p1, P(X=x2)=p2, n P(X=xn)=pn E(X) =
