    Planes in R3 Properties: Are They Parallel or Intersecting?

    Actually, I get it. A is true but B is false. Am I right on this? Skew is like one of them for example is a straight line to the right and the other one in the bottom of it towards me. Its not a good example but I hope its right.

    if two lines are skew they are neither intersecting nor are parallel

    Finding the Speed and Direction of a Woman on a Moving Ship

    I have gotten the first part of the question right. But when it comes to second one. I did arctan(23/3) which gave me 82.6*. But I am not sure of the direction in this case because the question wants the input as "direction N _____ *W" btw. * = degrees in this case.

    Problem solving Periodic Function

    the 3rd question asks for the period of the function. I don't understand it because its not a harmonic function or anything to have a period. How should I attack the question in this case? EDIT: Found the answer. I just thought that a period is time when it makes once cycle which is when it...

    Problem solving Periodic Function

    A=70 is given. I found 2.5 from the previous question: In the decreasing portion of the graph, what is the value of the time t (in s) for which V3(t)=0. Answer: 2.5 What I tried to do was to actually take the domain for the slope [1.0, 2.5] which will lead me to the range [70,0]. Can I do...
