2. Given the vectors u =<1, -2, 4> and v = <3, 5, 1>: a. Recall that ||u× v|| = ||u||||v|| sin 0 (area of the parallelogram defined by the vectors u and v). This offers a method for finding an angle between these vectors in addition to the dot-product approach. Use this to investigate the angle between these vectors (to the nearest 0.01°). b. Use the dot product approach for finding the angle between two vectors (to the nearest 0.01°). The dot - product involves the cosine of the angle between the vectors. c. Compare the two angle results above. Explain/illustrate the relationship between them. HINT: Think about and use your understanding of inverse trigonometric functions to explain the results. What is the correct angle? 0.5 =1 -0.5 0 0.5 -0.5-
