First and foremost, apologies for my poor typings. I have to do this on my iPhone: Given cos 3x = cos 2x. → Equation 1 We know that the function cos (x) is periodic, with period of 2π.

Finns någon vänlig själ där ute som har någon minut över och kan förklara lösningen så ja ser va ja missat: 1-tan^2x / 1+tan^2x = Cos2x

Cosine 2X or Cos 2X is also, one such trigonometrical formula, also known as double angle formula, as it has a double angle in it. Because of this, it is being driven by the expressions for trigonometric functions of the sum and difference of two numbers (angles) and related expressions.

You can put this solution on YOUR website! sin^2x(1+cot^2x)=1 distributing the sin^2x: sin^2x + sin^2xcot^2x = 1 substitute identity of "cot^2x" = cos^2x/sin^2x: sin^2x + sin^2x(cos^2x/sin^2x) = 1

Our math solver supports basic math, pre-algebra, algebra, trigonometry, calculus and more. Cos^2x-sin^2x = cos 2x.

Gib die ersten zwei Ableitungen folgender Funktionen an: a) f(x) = sin(x) b) f(x) = 2 sin(x) c) f(x) = sin(2x) d) f(x) = sin(x2) e) f(x) = cos(x) f) f(x) = 2 cos(x).

What do you want to do with it? I will say that (cos(2x)) 2 means: First calculate 2x, then find cosine of that and finally square that result. Notice that it is still 2x, not 4x.
