It could be that they are seeing cos as a constant, or maybe they're thinking there's a trig identity they can use. As for the product rule, it might help to tell them that you need two expressions that are being multiplied and both should involve the independent variable. In any case, it doesn't hurt to quickly go over functions with them.<br /><br />Even if they're still a little unsure, practice makes perfect.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-7806043650549721218.post-84339195671555702232012-07-13T16:11:59.745-05:002012-07-13T16:11:59.745-05:00I totally agree--it should be easy. Unfortunately...I totally agree--it should be easy. Unfortunately, many of my students still struggle with recognizing composition functions as such. For example, when asked what rule to use to differentiate the function f(x)=ln(3x+5), the response was the Product Rule. Similarly, for expressions such as x+xcos(2x), students have asked why we can't factor out the x in the argument. It seems (to me) that they think trig functions and log functions can be treated as constants.<br /><br />I really like the idea of presenting the "inside" function as an expression that involves the independent variable. I am certainly going to try it!

It's just a matter of identifying that function. If you can identify trigonometric functions, power functions, the exponential function and so on, it should be easy.Anonymousnoreply@blogger.com
