Calculus
The linear approximation at x = 0 to sin (5 x) is A + B x. Find A and B?

Math
Use linear approximation, i.e. the tangent line, to approximate 1.6^3 as follows: Let f(x) = x ^3. The equation of the tangent line to f(x) at x = 2 can be written as y=12x-16 Using this, we find our approximation for 1.6 ^3 is ???????

Math
Consider the function f(x) = 7 x + 3 {x ^ -1 }. For this function there are four important intervals: (-infinity, A], [A,B),(B,C), and [C,infinity) where A, B and C are either critical numbers or points at which f(x) is undefined. Find A, B and C
