Solve the initial value problem. ds dt = cost – sint, s (7) = 3 NOTE: This question is bonus, worth 5 points. Os=sint + cost + 2 8 = sint + cost +4 None of them 8 = sint - cost + 2 8=2 sint + 1
which one is right? cost 2 + a. sin o cos o sint rect csct b. -2 tan^0 C. 1 + cott d. sint tant
x1 + cost y = 4 + sint (You are welcome to use your calculator for this one.) ОА ов. O C. OD.
Given that yy(t) = cost is a solution to y" – y'+y=sint and yz(t) = 3 is a solution to y" – y'+y= 221, use the superposition principle to find solutions to the differential equations in parts (a) through (c) below. (a) y" - y' + y = 20 sint A solution is y(t) = 0
What's the difference in motion for these 3? x-t y-t r - sint y sint What's the difference in motion for these 3? x-t y-t r - sint y sint
Given ř(t) =< 2 cost, t, 2 sint > as a trace of a moving object. (a) Find the curvature of K(t). (b) Find the arc length when 0<t <31. (c) Find the unit normal and binormal vectors of F(t).
(22 - y2 + 2)ds, here C is the curve r(t) = (3 cost, 3 sint, 4t) with 0 <t<2.
