I have the following function in terms of time:
I know the differentiation with respect to t is:
However, I don't know how to do the differentiation to get that answer. I know the chain rule needs to be used, but I don't know exactly how to use it. Could someone please help me understand? My textbook is not as clear as I had hoped, and it unfortunately skips steps.
Thanks so much for the replies!
More explicitly, is this what's going on?
and from there straight to your last line.
Just in case a picture is of interest...
... and, zooming in on the inner derivative...
... is the chain rule. Straight continuous lines differentiate downwards (integrate up) with respect to t, and the straight dashed line similarly but with respect to the dashed balloon expression (the inner function of the composite which is subject to the chain rule).
