Find the area of the polar equation
r = 4cos θANS-A = (1/2) ∫(4cos θ)^2dθ from [0, 2pi]
plug into calculator
A = 8pi + 8sin(pi)
Find the area inside the first curve R = 2 + sin θ and outside the
second curve r = 3sin θANS-Find the positions of intersection by
setting the equations equal to each other and solving for θ.
Find the midpoint Riemann Sum of cos(x^2) with n = 4, from [0,
2]ANS-Mid S4 = (1)(1/2)[cos(.25^2) + cos(.75^2) + cos(1.25^2) +

If the function f is continuous for all real numbers and if f(x) = (x^2-7x
+12)/(x -4) when x ≠ 4 then f(4) =ANS-Factor numerator so
f(x) = (x-3)(x-4)/(x-4) = x-3
f(4)=4-3
f(4) = 1
If f(x) = (x^2+5) if x < 2, & f(x) = (7x -5) if x ≥ 2 for all real numbers x,
which of the following must be true?
I. f(x) is continuous everywhere.
II. f(x) is differentiable everywhere.
III. f(x) has a local minimum at x = 2.ANS-At f(2) both the upper and
lower piece of the discontinuity is 9 so the function is continuous
everywhere.
At f'(2) the upper piece is 4 and lower piece is 7 so f(x) is not
differentiable everywhere.
