Calculus Distraught Part 2
Homework:
What is the slope of the tangent line to the graph of y = x^3 at the point (2,8) ?
12
Consider the parabola given by the equation y = x^2 + 4x - 5. At which point on the graph of this parabola is the slope of the tangent line equal to 10?
(3,16)
The line y = 2x - 9 is tangent to the parabola y = x^2 + ax + b at the point (4,-1). What are the values of a and b?
-3,-6 respectively.
circle with equation x^2 + y^2 = 25. Which is the equation of the tangent line to the circle at the point (3,4)?
3x + 4y = 25

Re: Calculus Distraught Part 2
First one is correct!
In mathematics, you don't understand things. You just get used to them.
Probability is the most important concept in modern science, especially as nobody has the slightest notion what it means.
90% of mathematicians do not understand 90% of currently published mathematics.

Re: Calculus Distraught Part 2
The second one is correct. The third one isn't.
The limit operator is just an excuse for doing something you know you can't.
