Given that f "= - 12 (x-2) ^ 2 + 4, estimate the error obtainedby approximating the integral of f (x) on the interval [1.5,2.5]with n = 4, using trapezoids.
Find the domain of the vector function r(t)=find the equation of the plane that passes through the point(-1,3, -8) and is parallel to the plane 3x-4y-6y = 9
find the equation of the line parallel to the plane 2x + y + z =8 that passes through the point (1,2,3)
