I'm david and i'm here to help you answer your question.
00:02
In the question here, we are going to discuss about the derivative rule.
00:06
The first rule i want to review to you will be the caution rule.
00:10
It will the view over the derivative and it will equal to the u prime v minus the v prime u, divided by the v square.
00:21
And derivative of the side x, it will equal to the cosine of the x, derivative of the cosine x, it will equal to the minus side x, and the x power n, derivative equal to n times x power minus n.
00:39
And now in this question here, we're given the function fx equal to the size of the x, divided by the cosine of the x, again plus the square root of the x.
00:51
The question asks me to find the f -bram of the x.
00:55
So first of the fun, we need to apply the question rule, this will be the u and this will be the v...
