How do you find a derivative? Expand cos(2x)^2. Use the double-angle identity to transform to . Rewrite as . Expand using the FOIL Method.

cot^2x-cos^2x = cos^2x/sin^2x-cos^2x = (cos^2x-cos^2xsin^2x)/sin^2x = (cos^2x(1-sin^2x))/sin^2x = (cos^2x xxcos^2x)/sin^2x = (cos^2x/sin^2x xxcos^2x Cos 2x is also called a Double angle formula as they have 2 or double angles in the trigonometric functions.

2. ∫ cos(2x)dx. = 1.

You should have $$\int\cos(2x)\cos(3x)\,dx=\frac{\cos(2x)\sin(3x)}3-\frac{2\cos(3x)\sin(2x)}9+\frac49\int\cos(2x)\cos(3x)\,dx.$$ From there, product-to-sum laws should get you the rest of the way (though it would be easier to simply use them from the start). Steps on how to integrate sin(2x)cos(2x) using the u-substitution method.Begin the integral by using u-substitution where u=sin(2x), and then simplify the in Lämpliga formler: cos(2x) = 2cos(x)^2 - 1 och sin(2x) = 2sin(x)cos(x) Vilket då ger oss: cos(x) = 2cos(x/2)^2 - 1 och sin(x) = 2sin(x/2)cos(x/2).
