Answer 1

@ganeshie8 @perl

Answer 2

@mathmath333

Answer 3

Could you possibly take a picture also of the values you got for A-D? Or type them out here? :)

Answer 4

seems like it is for 100 marks

Answer 5

Oh,then this is considered cheating is it not.. -.-

Answer 6

we must perform individual mathematical operation... ahm i think i should start with sinh inverse?
please teach me how?

Answer 7

Your professor must be a psycho :O
here are few hints to get you started :

1) multiplication and division is easy in polar form
2) addition and subtraction is easy in rectangular form
3) \(\log_2 (re^{jx}) = \dfrac{\ln (re^{jx})}{\ln 2} = \dfrac{\ln r + jx}{\ln 2}\)

Answer 8

4) \(\overline{a+jb} = a-jb\)

Answer 9

Does the line mean conjugate? I wasn't sure.

Answer 10

in what part is that?

Answer 11

yes, for taking conjugate in polar you can just take the negative of angle

Answer 12

5) \(\overline{r\angle \theta} = r\angle -\theta \)

Answer 13

@KarlaKalurky dont get scared, start by working the innermost fraction

Answer 14

oh... :) hihi
so should we assign values for A, B, C and D?

Answer 15

work this first
\[\frac{(A\overline{B})^4 + \log_2 (C+D)}{\log_B A - \ln (D^{1/4})}\]

Answer 16

yes assign the values from previous table

Answer 17

aahhh oh i see :D THANKS! i'll be back with my answer lol thanks thanks!

Answer 18

@ganeshie8 is it
\[\log_{2}(re ^{jx}) \]
or
\[\log_{2}(re ^{j \theta}) \]
? :)

Answer 19

Ah yes it should be \(\theta\)
