Detailed explanation-1: -In vector operations, geometric techniques are more accurate than mathematical techniques.
Detailed explanation-2: -True/False: In vector operations, geometric techniques are more accurate than mathematical equations. False, mathematical equations will always be more accurate.
Detailed explanation-3: -A vector can be resolved into many different vectors, for resolution of vectors. For Example: Let us consider two numbers, say, 4 and 6, which is further added to obtain 10. Further, now 10 is broken or resolved. However, the number 10 can also be resolved into many other numbers like –10 = 5 + 5; 10 = 3 + 7 etc.
Detailed explanation-4: -To determine the resultant, the three individual vectors are resolved into horizontal and vertical components. The angle information about each vector is used to form a right triangle in which the vector is the hypotenuse and the perpendicular sides are oriented along the east-west and north-south axes.
Detailed explanation-5: -Resolution of a vector is the process of splitting up a vector (force) into two perpendicular component parts. They are called rectangular components because the two component forces are mutually perpendicular. Therefore the horizontal component of the force R is Rcos.
