True of false

Given the integral f va2 + b2x2 dx, you should use the trigonometric substitution bac = a sin(u). All definite integrals can be evaluated exactly using the techniques in this course. The distance travelled S by an object moving with continuous velocity v(t) along a straight line from time t = a to t = bis S = fo lu(t) | dt. foerdx = 1. 0 dx is always equal to 0
