- How do you add (-8-9i)+(3-6i) in trigonometric form? | Socratic
For a complex number a +bi we can repesent this in trigonometric form, as z = r(cosθ +isinθ) r = √a2 + b2 θ = arctan(b a) So, for z1 = − 8 − 9i, we can find that r1 = √(− 8)2 +(−9)2 = √145 θ1 = arctan(−9 −8) However, −8 − 9i is in quadrant 3, but θ is in quadrant 1, so we need to add π θ1 = arctan(−9 −8) +π ≈ 3 9857 z1 ≈ √145(cos(3 9857) + isin(3 9857

Number of protons=92 Number of neutrons=146 "_92^238"U" is chemical symbol of one of the isotopes of element uranium Some times it is also written as "U"-238 By convention the figure 92 is the atomic number of the element represented Atomic number is number equal to the number of protons in its nucleus And the other number 238 represents the Atomic mass of the element in amu (atomic mass
- Question #48bcb + Example - Socratic
From this, the number of unpaired electrons seems to be: Number of unpaired electrons = S |ms| = 2 145 1 2 = 4 29 ≈ 4 So it looks like treating μS+L ≈ μS for Fe2+ is OK to determine the number of unpaired electrons For Fe3+ it should be that μS+L = μS perfectly, since the 3d is half-filled there
