Question:
The answer given in the textbook is option d. What if I take iota outside the bracket which gives
(iota)^4 (cos theta + iota*sin theta)^4
1*(cos 4theta + iota*sin 4theta)
Which means option c. What am I doing wrong?
How to find $\lim_{h\rightarrow 0}\frac{\sin(ha)}{h}$ without lhopital rule? I know when I use lhopital I easy get $$ \lim_{h\rightarrow 0}...
