Find the angle made by ˆ i 3j with y-axis
WebWhat angles does the vector 3i+√2j+k make with y-axis? 66 degrees details Let A = 3i + sqrt (2)j +k and the y axis =j Use the dot product, A*j = A j cos b where b is the angle between vector A and the y axis Now i*j 0, k*j =0, and j*j =1 so A*j = sqrt (2) The magnitude of A ( A ) is sqrt 12, it equals (3^2 + 2 +1)^0.5 The magnitude of j ( j ) =1 WebThere are two formulas to find the angle between two vectors: one in terms of dot product and the other in terms of the cross product. But the most commonly used formula to find the angle between the vectors involves the dot product (let us see what is the problem with the cross product in the next section).
