I need to put 3e^(.5i) in rectangular and polar forms. i being imaginary number and .5 being in radians. When i convert .5 radians into degrees i get 28.6 degrees. When i do the math i get 3(cos28.6 + i*sin28.6) for the polar form. But i have no idea how to get the rectangular form from here. Pretty much working backwards.
If I'm doing a question similar to this except i have to put it in exponent form and i end up with something like 5e^(38.9 degrees*i) should i always convert the degrees to radians in this? And btw I'm not exactly sure by what you mean multiply it out. You want me to multiply the polar form out?
