We have 2 sinusoidal functions:
$f(x)= 0,30+2\sin (3x-\frac{1}{2}\pi$) and $g(x)=0,30+2\sin(3(x-\frac{1}{2}\pi))$.
What would happen to both functions if you performed a translation of let's say $(3\pi;0,10)$?
What would happen if you multiply with reference to the y-axis (I believe in English it's called a horizontal stretch) of f(x) and g(x) with $\frac{1}{5}$?
I have to do this in a test in 2 hours but nowhere in the book do they explain transformations of already 'complete' sinusoids (of the form a+sinb (c(x-d)) ) , I understand transformations, however this is the last thing I must know, you guys on mstackexchange have helped me a lot, since I've missed every single lessson this past month I had you guys as my 'teachers' and I'm sorry for some of my boring questions.. this is the last one, after that my questions will be better , I promiss.
