Detailed explanation-1: -You can also find vector components by using the angle measured counter-clockwise from the +x axis. In that case, the x-component will always correspond to cos and the y-component to sin.
Detailed explanation-2: -Step 1: Identify the given value of velocity (v ) and its direction ( ) with reference to the horizontal direction (x-axis). Step 2: Use the formula vx=v(cos) v x = v ( c o s ) for x-component (horizontal) and vy=v(sin) v y = v ( s i n ) for y-component (vertical) of the velocity.
Detailed explanation-3: -If a position vector has a magnitude of r and a direction angle of , then the components of the position vector are given by the following formulas: Horizontal Component (x-component) = rx=rcos r x = r cos
