Step 1: The transfer function of the forward path is given by: $G(s) = G_1(s)G_2(s) = \frac{1}{s} \times \frac{1}{s+3} = \frac{1}{s(s+3)}$ Show more…

Consider the table of values shown below: $x$ | $f(x)$ | $g(x)$ | $f'(x)$ | $g'(x)$ ---|---|---|---|--- 1 | -2 | 0 | $pi$ | 11 2 | 2 | 3 | 3 | 1 3 | 4 | 1/2 | -5 | -1 4 | 2 | $pi$ | -3 | $e$ Evaluate the derivatives $y'$ of the functions at the indicated $x$-value using the table above, or explain why the derivative does not exist. (a) $y = [f(x)]^3 - frac{g(x)}{2}$ at $x = 1$ (b) $y = 17 - 5e^{f(x)}$ at $x = 2$ (c) $y = ln(f(x)) + 3xg(x)$ at $x = 3$ (d) $y = frac{4f(x)}{g(x)} - sin(g(x))$ at $x = 4$ (e) $y = x^7 + frac{1}{3}g(f(x))$ at $x = 1$

Farnesyl pyrophosphate is an important precursor in the biosynthesis of many sesquiterpenes. Starting with farnesyl pyrophosphate, draw curved arrows that would give intermediate X. Redraw intermediate X (yes, part of the challenge of this problem) and provide curved arrows towards the formation of b-caryophyllene.
