(a) f (x) = 2x (b) g(x) = sin(3x) x (c) let h(x) = z x2+6 (sin(3t) t) (d) find dy/dx, where y = ex+y. Find h (x): (5 points each) calculate the following integrals. 2x + 3x2 (a) z sec2(cos x) sin x dx (b) z 2 (c) z e x3+3x(x2 1) dx (d) z 0. 4x3: (10 points) use the (limit) de nition of the derivative to compute g (x), where g(x) = 1: (15 points) you"re watching the boston red sox play a baseball game against the. The baseball diamond the teams are playing on has the shape of a square, with 80 ft. between bases, and the pitcher"s mound in the exact center. Boston player david ortiz runs from 2nd base to 3rd base at a rate of 20 ft. /sec.
