Hey guys, I need help on a type of problem that I just can't seem to get and I have a math test tomorrow. I need to know how to graph sinusoids. For example:
The 3 tells you that its period will be compressed by a factor of 3. Your new period will be \(\displaystyle \L\\ \frac{(Old Period)}{3}\) In cosine's case \(\displaystyle \L\\ \frac{2\pi}{3}\)
The +1 tells you a shift upwards of 1
The 5 outside tells you the amplitude. The original curve goes from -1 to 1, but now it will go -5 to 5
x - 50 is the angle. This tells you it will be shifted to the right by 50.
