Chain rule applies as usual. We would be differentiating sin x otherwise, but instead, we are differentiating sin 4x, so we have to differentiate the chain '4x' as well. Similar argument applies for cos 0.5x.
Remember that differentiating sin x gives cos x and differentiating cos x gives -sin x.
Remember that differentiating sin x gives cos x and differentiating cos x gives -sin x.
