Answer:
1+pi/2, 5/2, square root of 12-1, 2.25. Let me know if this is correct!
Step-by-step explanation:
Answer:

Step-by-step explanation:
<u>Step(i)</u>:-
Given z 1 = 3(cos 37° + i sin 37°)
z 2 = (cos 53° + i sin 53°)
by using complex numbers


<u><em>step(ii)</em></u>:-
now

z ₁ = 3(cos 37° + i sin 37°) = 3 c i s 37°
z ₂ = (cos 53° + i sin 53°) = c i s 53°
we will use formula



<u><em> Conclusion:</em></u>-

Answer:
Dimensions of a matrix:
r × c
Where r is the no. of rows and c is the no. of columns
If A has 4 rows (horizontal) and 3 columns (vertical),
Dimensions are: 4 × 3
If A has 3 rows (horizontal) and 4 columns (vertical),
Dimensions are: 3 × 4
