  1. Ask your question and show the work you've done so far. If you've posted a screenshot of a question, specify which part you need help with.
  2. Wait patiently for a helper to come along.
  3. Once someone helps you, say thank you and close the thread with:
    +close
    
  4. Feel free to nominate the person for helper of the week in #helper-nominations
  5. Do not ping the mods, unless someone is breaking the rules. If there is a conflict amongst multiple helpers feel free to ping “Helper Mod”
  6. If you're happy with the help you got here, and the server overall, you can contribute financially as well:

i'm not sure because i know the range only reaches 1 and -1 for sin x and cos x

#

use the complex definition of sine

#

$\frac{e^{iz}-e^{-iz}}{2i}=3$

#

in this case we set it equal to 3

in the complex definition of e^iz

#

i want to say that there aren't any, because even complex numbers follow sin^2(x) + cos^2(x) = 1

twilit herald
#

i have a general formula

#

somewhere

twilit herald
#

just search it up

there can't be solutions if cos(x) = sin(x) = 3, as this will not follow the pythagorean identity

#

which is shown to hold true for complex numbers

#

oh thats what you mean

#

are you trying to solve them seperately or together?
