0 940 2 How do you graph parametric equations?Y = A cos w(x – π), the period is 2 π / w and the phase shift is π (the beginning of one period) Rewriting the given equation to this form, y = 5 3cos 2(x – π/3) Therefore, period = 2 π / 2 = π phase shift = π /3 So to create two periods, you need an interval of 2 π If you start at π /3, you'll start and end at the max ofStep 2 As sin(0) = 0 so sine graph starts from the origin or you can say that sine graph cuts the Xaxis at (0,0) And sin(π/2) = 1 which is maximum for this particular graph since the amplitude is 1 so the sine curve is up to π/2,1

Test for each of the three types of symmetry 1) Replacing (r, θ) with ( − r, − θ) yields the same result Thus, the graph is symmetric with respect to the line θ = π 2 −r = 2sin(−θ) −r = −2sin θ Evenodd identity r = 2sinθ Multiply by−1 Passed 2) Replacing θGraph π/2 units left we get the cosgraph can be written cos(x) = sin(2 πx) and since cos(x) = cos(–x), this can be also written cos(x) = sin(2 π–x) The second relationship between sin and cos comes from the Pythagorean Theorem applied to the bold triangle at the right sin2(x) cos2(x) = 1Looking again at the sine and cosine functions on a domain centered at the yaxis helps reveal symmetriesAs we can see in Figure 6, the sine function is symmetric about the origin Recall from The Other Trigonometric Functions that we determined from the unit circle that the sine function is an odd function because latex\sin(−x)=−\sin x/latex
The concept is related to having a switch in an electronic circuit open for a period of time (so there is no current flow), then the switch is closed (so the current begins to flow) Example 1 Products with Unit Functions (a) If `f(t) = sin t`, then the graph of `g(t) = sin t One of the following graphs in the standard (x,y) coordinate plane is the graph of y = sin 2 x cos 2 x over the domain − π/2 ≤ x ≤ π/2 Which one?Free graphing calculator instantly graphs your math problems

To draw the graph of one period of sine or y = sin x, label the xaxis with the values 0π, π 2, π,3π 2, and 2π Then plot points for the value of f(x) or y from either the table or the unit circleAnalyzing the Graphs of y = sec x and y = cscx The secant was defined by the reciprocal identity sec x = 1 cos x sec x = 1 cos x Notice that the function is undefined when the cosine is 0, leading to vertical asymptotes at π 2, π 2, 3 π 2, 3 π 2, etc Because the cosine is never more than 1 in absolute value, the secant, being the reciprocal, will never be less than 1 in absolute valueAnd here is how it looks on a graph Note that we are using radians here, not degrees, and there are 2 π radians in a full rotation Example sin(x) This is the basic unchanged sine formula A = 1, B = 1, C = 0 and D = 0 So amplitude is 1, period is 2 π, there is no phase shift or vertical shift Example 2 sin(4(x − 05)) 3
