With precalc vectors? medal and fan v = (-7,8) find the magnitude of vector v. express your answer in radical form sqrt of 113 is what i got for that. second part: use the magnitude and the angle of vector v to write it in the form (lvlcostheta, lvl sin theta). i don't know how to determine the single angle for one vector. earlier in a different part of the problem, i was asked to find the angle between two vectors, but i don't think you use that here since no second vector is provided. so how would i answer the second part? (:
