Trigonometry: Amplitude, Reflection & Period/Vertical & Horizontal Translations (Sections 4.2 & 4.3)

Examples graphing sine and cosine functions that have changes to their amplitude and period, have been reflected and/or shifted vertically/horizontally (phase shift). Step by step breakdown of how to find all relevant characteristics and graph one period using five key points. #amplitude #period #phaseshift #translation #mathtvwithprofessorv #trigonometry #graphing #triggraphs #sine #cosine #domain #range #mathvideos #youtubemath #mathprofessor #calculus #precalculus

Professor V, thank you for another amazing video/lecture on Amplitude, Reflections, Period, Vertical and Horizontal Shifts in Trigonometry. In some Trigonometry books and also on YouTube, finding the phase shift, Bx -/+C is equal to zero. If you solve for x, then this is your phase shift. I also encountered this topic in Engineering Physics I, II and III.
