Let r(t) = (4t - 1, cos(2nt), el-4ty. 1. Find the corresponding t-value for the point (0, 0, 1). t (enter an integer or a fraction; must simplify your answer) 2. Find parametric equations of the tangent line to the curve r(t) at the point (0, 0, 1). X = 4t y = Z = 1+ ter pi for IT ; for example, 2pi fpr 27 and -2pi for -271 ; no space, no multiplication erator, and no parentheses)
