In the first problems, calculate f'(x)
In the first problems, calculate f'(x) · x'(t) when t = 3 and use
these values to determine the value of d/dt (f(x(t))) when t = 3.
1) f(x) = tan^3(x), x = 8
————————————————————————————————————————————————————————————————-
2) f(x) = 2x + cos(x) so f(0) = 1. Without graphing the function, you can be certain that f has how many positive roots?
————————————————————————————————————————————————————————————————-
3)calculate the limit of each expression as “x→ ∞.”
4 – 3x / x + 8
