Starting with sin 2 x and using the chain rule to take its derivative we have 2sin x cos x Now by the product rule we multiply this by our second term cos 2 x so the left side of the derivative is 2sin x cos x cos 2 x or 2cos 3 x sin x Now for the right side we use the chain rule to take the derivative of cos 2 x 2cos Calculus Differentiating Trigonometric Functions Differentiating sin x from First Principles 1 Answer crayon
When we have a function of x like y x sin x where a single term contains x in both its base and its power perhaps the easiest way to find the function s derivative is to first take the natural logarithm of both sides ln y ln x sin x color white ln y sin x ln x This places all the x s on the same level Let s start off with what we know intcosxdx sinx because the derivative of sinx is cosx We just have to adjust for that pesky 2 Let s think for a moment intcos2xdx essentially means that if we take the derivative of our solution we should get cos2x

To derive u in terms of x we need to apply chain rule once more Let u sin v v x du dv cos v dv dx 1 2 x 1 2 1 2 x Hence du dx du dv dv dx cos x 1 2 x cos x 2 x Now that we know du dx we can find dy dx dy dx dy du du dx 2 sin x cos x 2 x sin x cos x x Answer Solving this for cos2 x shows us that cos2 x cos 2x 1 2 Thus cos2 x dx 1 2 cos 2x 1dx We can now split this up and find the antiderivative 1 2 cos 2x dx 1 2 1dx 1 4 2cos 2x dx 1 2x 1 4 sin 2x 1 2 x C 1 4sin 2x 1 2x C The trick to finding this integral is using an identity here specifically
