- But no explicit connection, such as “dx is the limit of \(\Delta x\) as n increases without bound” or something like that. Then we get to the section on u-substitution, which opens with considering the calculation of \(\int 2x \sqrt{x^2+1}
- so we need to find when this is at a minimum, i.e. the slope is equal to zero. The derivative is just a lot of product rule differentiation. dl/dx = 1/2*[2x + 8(4x +7)]/[x^2 + (4x + 7)^2]^(1/2) = 0 Solve for x... then plug determine y from y = 4x + 7 and ...

Another trigonometric integral problem, this one is the integral of x times cosine ... take the derivative of u which we account du. So du is 2x, you get 2x from the x2 and the derivative of 1 is just 0 and then always remember to add the dx on to the ...- Use the chain rule to obtain the formula for d (arcsin x). dx d (log x). 45. Using the chain rule ... The best quadratic approximation has the same ﬁrst and second derivatives as y = ln x at x = 1. (b) Use a computer or calculator to graph the ...
