Primitiv funktion e^3x - att bestämma primitiva funktioner till potens

Övning 9 Bestäm alla primitiva funktioner till a) sin(5x)cos(x), b) sin4(x)cos2(x), c) e2x sin(3x). Övning 10 Bestäm en primitiv till var och en av följande funktioner: a) sin(2x) cos3 x, b) cos x sin x+ 2, c) 1 2cos. cos(2x)=cos^2(x)-sin^2(x). Detta kan du få fram genom att sätta cos(2x)=cos(x+x)=cos(x)cos(x)-sin(x)sin(x)=cos^2(x)-sin^2(x).

So we get: sin(x + x) = sin(2x) = sin(x)cos(x) + cos(x)sin(x) = 2sin(x)cos(x) Therefore Borde bli (sinx)^3/3cosx, men det stämmer inte när jag deriverar. Hälsningar Hans L 2015-07-28 · y^' = -2/(sinx - cosx)^2 Start by taking a look at your function y = (sinx + cosx)/(sinx - cosx) Notice that this function is actually the quotient of two other functions, let's call them f(x) and g(x) {(f(x) = sinx + cosx), (g(x) = sinx - cosx) :} This means that you can differentiate this function by using the quotient rule, which allows you to find the derivative of a function that's the Trigonometric Identities and Formulas. Below are some of the most important definitions, identities and formulas in trigonometry.

Cos (x)= alternate side/hypotenuse. So when we divide sin (x) and cos (x) We get.
