Vector A has a magnitude of 18 (in some unspecified units) and makes an angle of 25 with the x axis, and a vector B has a length of 24 and makes an angle of 70 with the x axis. Find the components of the vector C in the following:
(a) C = A + B
(b) C = A - B
(a) θ=25° φ=70°
Cx = Ax + Bx = |A|cos(θ) + |B|cos(φ)
= 16.31 + 8.21
Cy = Ay + By = |A|sin(θ) + |B|sin(φ)
= 7.61 + 22.55
(b) similar to (a), but subtract instead of add.
