WebOmar. First, draw the vectors on any piece of paper. One way to approach this problem is to draw one vector that has an angle of elevation of 0 degrees, which just means that's parallel to the x-axis, and draw the other vector with an angle of elevation of 60 degrees. Let's assume that vector A is horizontal, and vector B is elevated at an ... WebI think there's only one answer that fits the question. You are right that arctan(7/-10) yields two answers in the range 0-360 degrees, but the vector u is in the second quadrant (u= … irish driving hats for men
Finding the Angle a Given Vector Makes with the Positive x-axis
WebSteps for Finding the Direction Angle of a Vector in Unit Vector Form. Step 1: Identify the horizontal component of the vector. Step 2: Identify the vertical component of the vector. … WebMar 10, 2015 · This means that if you give a number to the arctangent function, most calculators respond with an answer between − 90 ∘ and 90 ∘. This is the half-plane on the right, quadrants I and IV, so x is assumed positive. If x is negative, the answer you want is 180 ∘ away. Share. WebDec 24, 2016 · Further explained: The formula used above to find the magnitude of the vector comes from Pythagorean theorem. If we were to graph the vector <6,-6>, we would draw an arrow from the origin to the point (6,-6). This is equivalent to moving 6 units in the positive i or x direction and 6 units in the negative j or y direction. porsche suffolk county
