In the complex number 4 + 2i, 4 is the

4 is the real part

2i is the imaginary part

Step-by-step explanation:

In complex number a+ib

'a' is the real part and ib is the imaginary part

All complex numbers comes with real part and imaginary part

The number without 'i' is always a real part

the term that has 'i' is an imaginary part

In the given complex number, 4+2i

4 is the real part

2i is the imaginary part

intensity of the vector is v= √37 ≈ 6.08 units and make angle ∡α ≈ 9.46° with east direction

step-by-step explanation:

required vector is consists of the two componentsvx= 2+4=6 units   and vy= 1 unit and vx ⊥ vywe will use pythagorian theorem to find intensity of the vector vv∧2 = vx∧2 + vy∧2 => v = √vx∧2 + vy∧2 = √6∧2 + 1∧2 = √36+1 = √37 ≈ 6.08 unitsthe angle ∡α between vector and east direction we wil find with tanαtanα = 1/6 => α = arc tanα = arc 1/6 => α ≈ 9.46°
