(i) Sketch the graph of y = cos x for 0° ≤ x ≤ 360°. On the same axes, sketch the graph of y = cos 2x for 0° ≤x≤ 360°. Label each clearly. ii) Solve the equation cos 2x = 0.5 for 0° ≤x≤ 360°.

a)Estimate the area under the graph of f (x) = cos (x) from x = 0 to x = π/2 using four approximating rectangles and right endpoints. Is your estimate an underestimate or an overestimate?

Use a graphing calculator, Desmos, Wolfram Alpha, etc, to observe a graph of the function g (x) = 10 cos (x + 2) sin (x²). For this exercise, we'll focus on the interval between x = -2 and x = 2.

Graph several members of the family of curves with parametric equations x = t + a cos t , y = t + a sin t , where a > 0. How does the shape change as a increases? For what values of a does the curve have …

Transcribed Image Text: The shaded region in the figure above is bounded by the graph of y = cos TX and the lines x = -7, x = 7, 10 and y = 2. What is the area of this region?

Graph the curve x u0002= cos t + 2 cos 2t y =u0002 sin t + 2 sin 2t to discover where it crosses itself. Then find equations of both tangents at that point.

Find a function of the form y = A sin (kr) + C or y = A cos (kz) + C whose graph matches this one: 6+ 46 15 -14 -13 1 -10 8 9 10 2 Leave your answer in exact form; if necessary, type pi for 7.
