Let us equate, X and Y, i.e. X = Y. So, the above formula for cos 2X, becomes. cos 2X = cos(X + X) = cos X cos X– sin X sin X. cos 2X = cos2 X–sin2 X. Hence, the first cos 2X formula follows, as. cos 2X = cos2 X–sin2 X. And for this reason, we know this formula as double the angle formula, because we are doubling the angle.

Note that cosπ is …Feb 10, 2021 ... Quotient of Complex Numbers (1 of 2: Evaluating modulus) · Introduction to Calculus (2 of 2: First Principles) · Informal Proof of Euler's Formul... The classic 30° triangle has a hypotenuse of length 2, an opposite side of length 1 and an adjacent side of√ 3: Now we know the lengths, we can calculate the functions: Sine. sin (30°) = 1 / 2 = 0.5. Cosine. cos (30°) = 1.732 / 2 = 0.866... Tangent. tan (30°) = 1 / 1.732 = 0.577... (get your calculator out and check them!)
