Please help me сorrectly draw a mshoom on oscillocpe

Hi guys. I tried to make a mushroom in Audacity using this video https://youtu.be/rtR63-ecUNo. And everything went fine, but there were problems with the horizontal

oscillations of the fungus. the video says that you need to multiply the sawtooth by the cosine of a slightly different frequency. I did it in Excel, and then I imported it into Audacity through raw, but it turned out very strange. Please tell me what is wrong with me and how to correctly multiply the cosine by the sawtooth?
