3) Now, we can rearrange this to give: cos^2 (x) = (1+cos (2x))/2. 4) So, we have an equation which gives cos^2 (x) in a nicer form, which we can easily integrate using the reverse chain rule.

The key to solving any integral of this form is to use the cosine rule: cos (2x) = cos 2 (x) - sin 2 (x) = 2 cos2(x) - 1 = 1 - 2sin2(x) All of these forms are really helpful when solving problems such as this, and …

To find the Integral of (sinxcos^2x) dx, we must first use our knowledge of integration and differentiation of simple trigonometric functions. Such as Sinx and Cosx.

How do I integrate cos^2x with respect to x? This can be a very tricky question if you do not know how to approach it. Our first instinct may be to try a substitution, but this gets us nowhere. In fact, the trick is …

The second integral [ ∫ x/2 dx] is simple, integrating to x^2/4 For the first, trickier integral [∫ (xcos (2x))/2 dx], notice that this integral appears to be the multiple of two functions, so integration by parts is …

Find the indefinite integral of cos^2 x First, we need to write cos 2 x in a form that is easily integrable. We can use the double angle formula cos (2x) = 2cos 2 x - 1 to see that cos 2 x = 1/2cos (2x)+1/2. …

Find the integral I of e^ (2x)*cos* (x), with respect to x Because we have a product of two functions of x, our first instinct is to apply integration by parts. Let u = e^ (2x) and v' = cos (x). We then integrate v' …
