Since you have , what does that mean is?
So it starts like this:
Find the derivative of y = isinx + cosx
And I don't know what I'm supposed to do with the complex number so I just sort of left it and got this:
dy/dx = -sinx + icosx
Which is equal to i * y
Then it says to
1) find dy/y
2) use the condition x=0 to determine the value of c (constant of integration)
3) write this antiderivative in its equivalent form
I don't know what to do next! Please dumb it down as much as possible.
