Now that we are half-way through the semester, what challenges are you facing in this course?  How can you overcome them and persevere?    Is there anything else you want to tell me, either about yourself or about the class?

Determine whether the given function satisfies a Laplace equation:  

Find the limit.  Give exact answers only.  

Find the domain of the function. f(x, y) = cos-1(x2 + y2)

Find the limit.  Give exact answers only. 

Find the value.Find F(f(t), g(t))    if    F(x, y) = xy2    and    f(t) = t3 sin2t,    g(t) = 4 csc t Type your answer in the given answer box.  You may need to use the equation editor found in the editing menu.  If the equation editor is not showing, click on the three vertical dots to expand the menu.  Be sure to fully simplify your answer!!! (No fractions, no negative exponents, no radicals, least number of trig functions, etc.)

Find the specific function value.Find f(-8, -5) when f(x, y) = 2y2 – 9xy.

At what points is the given function continuous?

Find the value.Let

Calculate the arc length of the indicated portion of the curve r(t).r(t) = 10t3i + 11t3j + 2t3k ; -1 ≤ t ≤ 2
