1 cos 2x

När man deriverar sin(x) får man en annan trigonometrisk funktion, cos(x). Härledning. D(sin(x))=cos(x) Om man deriverar tan(x) får man cos2(x)1​.

So we have an equation that gives cos^2(x) in a nicer form which we can easily integrate using the reverse chain rule.

Statement 3: $$\cos 2x = 2\cos^2 x - 1$$ Proof: It suffices to prove that. $$1 - 2\sin^2 x = 2\cos^2 x - 1$$ Add $$1$$ to both sides of the equation: $$2 - 2\sin^2 x = 2\cos^2 x$$ Now add $$2\sin^2 x$$ to both sides of the equation: Answer to: Integrate: \int_0^1 \cos 2x dx By signing up, you'll get thousands of step-by-step solutions to your homework questions.
