-Use implicit differentiation to find dy/dx where
x2y2 + x cos(y) = 6
-Use logarithmic differentiation to find the derivative of o(x)
= (cos(x))ln(x)
-Find the first and second derivatives of p(x) = 6
ln(x2+3x)
-A balloon is rising vertically at a constant speed of 5 ft/sec.
A boy is
cycling along a straight road at a speed of 15 ft/sec. When he
passes
under the balloon, it is 45 ft above him.How fast is the
distance between
the boy...
part 1)
Find dy/dx by implicit differentiation.
3x^6+x^5y−2xy^6=8
dy/dx=
part 4)
A campground owner has 2000 meters of fencing. She wants to enclose a rectangular field bordering a lake, with no fencing needed along the lake: see the sketch.
a) Write an expression for the length of the field: 2000-x (this is correct)
b) Find the area of the field (length times width): -x^2+2000x (this is correct)
c) Find the value of x leading to the maximum area:
d)...
