Question

Plot this complex number in the complex plane and write it in polar form. Express the argument in degrees.
9 + 8i
Give your answer using the form z = A(cos(B°) + i sin(B°)), where A > 0; and 0° ≤ B° < 360° .

Answer 1

u know how to plot a point in xy plane, right ?

Answer 2

can u plot the point `(9, 8)` in xy plane ?

Answer 3

is that what you mean?

Answer 4

excellent! thats exactly same as the complex number 9+8i
