Homework Help Overview

The discussion revolves around various calculus problems, including continuous depreciation, asymptotes, normal lines, and average rates of change. Participants are exploring concepts related to exponential decay, limits for asymptotes, and the properties of tangent and normal lines in relation to functions.

Discussion Character

  • Mixed

Approaches and Questions Raised

  • Participants attempt to solve a problem involving continuous depreciation using the formula A = pe^rt, questioning the accuracy of their results.
  • There is discussion about finding vertical and horizontal asymptotes, with some participants questioning the use of limits and the conditions under which they apply.
  • Inquiries are made regarding the equation of the normal line at a specific point, with confusion about the slope and the relationship between tangent and normal lines.
  • Participants explore the average rate of change, with some expressing uncertainty about their calculations and the correct approach to finding the answer.

Discussion Status

The discussion is ongoing, with participants providing guidance and alternative approaches to the problems. Some participants express confusion and seek clarification on specific concepts, while others attempt to verify or challenge the reasoning presented. Multiple interpretations of the problems are being explored, indicating a productive exchange of ideas.

Contextual Notes

Participants reference textbook rules regarding the use of limits for asymptotes and express uncertainty about the application of calculus concepts, particularly in relation to finding slopes and equations of lines. There is a mention of impending exams, which may influence the urgency and focus of the discussion.

How would you find the complex zeros or radical in this case ( if there were not integer roots ) ? would i have more information if i had to find only complex zeroes?

Also, there was a questoin in a sample test where it said " Explain how you would find non-real roots in an equation using your calculuator".. Would I use the table and find it since the graph won't display complex roots?

I'm no specialist with (graphical) calculators but finding roots (whether real or complex) is always possible using formula until the degree of 4.

Well-known is the one for quadratic equations, using \frac{{ - b \pm \sqrt {b^2 - 4ac} }}{{2a}} where you get complex solutions if {b^2 - 4ac} is negative.

Find two triangles for which A=36 degrees , a= 16 and C=17

So do I first find all the angles and sides for the first triangle? What do I do next? Divide the triangle into two and then find the 2 angles of the divided triangle?
 
  • #34
Did you mean C = 17° the angle or c = 17 the side?
 
  • #35
i think c is the side.
 
  • #36
If you know A, a and c, you can use the law of sines:

\frac{{\sin A}}{a} = \frac{{\sin B}}{b} = \frac{{\sin C}}{c}
