Math 106: Exam I Prep - Area, Integration, Approximations, and Diff. Equations, Exams of Calculus

Review questions for exam i of math 106, covering topics such as finding areas under curves, decreasing and concave functions, approximations using various methods, integrals, and differential equations. Students are asked to find the area under sinx on [0, π], integrate e^(√x) dx, x^3 dx, and cos(3(5x)) dx. They must also order quantities related to a decreasing and concave up function and find approximations for the integral of f(x) = 12/(1 + x^2) dx using left, right, midpoint, trapezoidal, and simpson's rules. Additionally, students are asked to find bounds for errors in approximating the integral of ln(x) dx, estimate y(2.5) using euler's method, find the arc length of y = 1 - x^2, and write integrals for the volume of a rotated region and the work done in pumping fluid in a pyramid.
