Differentiation galore - Math 1A, section 103
1. Find the derivative of the function f(x) = 1/x.
2. Use derivative rules to compute the derivatives of the following functions with respect to x:
(a) f(x) = ex/1+x
(b) f(x) = ee^x
(c) f(x) = arcsin(3x)
(d) f(x) = ln(1 - x)
(e) f(x) = 2x + 3x
(f) f(x) = cos(arcsin(x))
3. Compute the derivative of (sin(x))3 by using the chain rule and by using the product rule. Do you get the same answer in either case?
4. Use implicit differentiation to find the tangent line to the circle x2 +y2 = 25 at the point (3, -4). What happens when you try to solve for y and find the derivative instead of using implicit differentiation?
5. Use implicit differentation to find the slope of the tangent line to a point (a, b) that lies on on the circle x2 + y2 = 1. Express your answer in terms of a and b.
6. Sketch the graph of the function f(x) = x3 - 2x. Find f''(-1), f''(0), and f''(2). What do you think the second derivative might tell us about the graph?
What the average variable cost and the average fixed cost
: Suppose the total cost of producing 40,000 flash drives is $120,000 and the fixed cost is $30,000. What is the variable cost? When output is 40,000 what the average variable cost and the average fixed cost?

What is the capitalized cost of owning and operating
: Diesel Locomotive are extreamley durable. The price of a new locomotive is $450,000 and if it is overhauled every 15 years at a cost of $75,000 it can be operated indifinetly. Annual operating cost (fuel, labor) are estamated at $150,000 a year. What..
