Combining two or more vectors to form a resultant vector.
Place them head to tail and draw the resultant vector.
The combined effect of the original vectors.
Magnitude is x2+y2\sqrt{x^2 + y^2}x2+y2 for components xxx and yyy.
Rx=Ax+BxR_x = A_x + B_xRx=Ax+Bx for corresponding vector components.
Angle θ\thetaθ is found using arctan(Ry/Rx)\arctan(R_y/R_x)arctan(Ry/Rx).
R=(4,2)R = (4, 2)R=(4,2) after adding components.
∣R∣=42+22=20≈4.47|R| = \sqrt{4^2 + 2^2} = \sqrt{20} \approx 4.47∣R∣=42+22=20≈4.47.
θ≈26.57°\theta \approx 26.57°θ≈26.57° above the positive xxx-axis.
It's precise and useful for solving complex problems.
