Quadric surfaces are the graphs of any equation that can be put into the general form. When you’re ready check out the function transformations solutions below: Solutions: In this section we are going to be looking at quadric surfaces. Think you are ready to try graphing trig functions and identifying the amplitude, frequency, period, vertical phase shift, and horizontal phase shift? Check out the practice questions and answers below! Practice Questions: Shift our entire graph y=2cos(x+(π/2)) up one unit along the y-axis to get y=2cos(x+(π/2))+1 All this means is that we are going to shift our entire graph up by 1 unit along the y axis. Step 5: For our last transformation, we have a vertical phase shift up 1 unit. Shift our graph y=2cos(x) over by 90º to the left to get y=2cos(x+(π/2)) To do this, we need to look at where negative (π/2) is on our graph at (-π/2) and move our entire graph over to start at this new point, “shifting” over each coordinate point by (π/2) along the x axis. Definition of the Trig Functions tan cot. Step 4: Next, we can apply our horizontal shift to the left by (π/2) or 90º. Re-draw y=cos(x), with an amplitude of 2 to get y=2cos(x)
