Uppgift 2. Derivera med avseende på x och ange för vilka x derivatan existerar! B. f(x) = cos(tanx) C. (1 + tan2 x2)2x − 2(tanx)(1 + tan2 x) för x = π/2 + nπ.
tan(A+ B) = tanA+ tanB 1 tanAtanB (8) tan(A B) = tanA tanB 1 + tanAtanB (9) cos2 = cos2 sin2 = 2cos2 1 = 1 2sin2 (10) sin2 = 2sin cos (11) tan2 = 2tan 1 tan2 (12) Note that you can get (5) from (4) by replacing B with B, and using the fact that cos( B) = cosB(cos is even) and sin( B) = sinB(sin is odd). Similarly (7) comes from (6).

∑ n=0 an n! xn för funktionen f(x) = tanx, det vill säga, 1.
Since the result is 2, it must mean that the opposite side divided by the djacent side equals 2. This only occurs whens the oppostie side is twice the adjacent side. Therefore it must be at an angle of 30 degrees. If you draw the 30-60-90 triangle this can be verified.
