Graph of cos(x) is symmetric about the y axis You get the same values as output for every pair of positive and negative input x Thus, cos(x) is an even function f(x) = cos (x) = cos (x) Check Let x = π/4 f(x) =Cos(π/4) =1/√2 f(x) = Cos(π/4) = 1/√2 = f(x) Here, we need to note that ( π/4) lies in the 4th quadrantCalculus Using the first and second derivative, sketch the graph of f(x) = sin(x) cos(x)Graph the function y = cos(x) 7 and explain how to find the number of times the gum returns to the wall as it travels a distance of 60 feet The gum returns to the wall each time the graph shows a minimum value of 6 (the height of the wall) Count the number of minimums that occur between x = 0 ft and x = 60 (but omit the first time when x = 0)

F(x)=cos x graph-Y y axis f (x)=f (x) f (−x) = −f (x) In other words, the graph is symmetric about origin f (0)=f (0)\implies f (0)=0 f (−0) = −f (0) f (0) = 0 That is, an odd function must pass through the origin From this definition, the cosine function is an even function and the sine function is an odd function f (x) = cosx ⇒ f '(x) = −sinx This is the graph of y = f (x) And this is a graph of its derivative y = f '(x)

To graph f (x) = 1 cos(x), start working on it's Parent Function f (x) = cos(x) first Make a table of values for f (x) = cos(x) and f (x) = 1 cos(x) For x, consider the values 0, π 2,π, 3π 2 and 2π If you examine Col 4 and Col 5, you see that the difference is 1 Graph of y = f (x) = cosThe roots or zeros of y = sin x is at the multiples of π; I was wrong when I wrote cos x (which is a function pair, so the graph of cos x is no problem) Actually, I wanted to do was make the graph of f (x) = sin x , and I thought I'd just ask a simple question (f(x) = sinx )and, after suggestions, I would complete the rest

Mac, we have two responses for you Hi Mac, I would be guided by the graphs of the sine and cosine near x = 0 For the cosine function, when x is close to zero (actually between π /2 and π /2), cos(x) = cos(x) and hence near x = 0 cos(x) = cos(x) and thus lim h>0 (cosh cos0)/(h) = lim h>0 (cos(h) cos0)/(h) = 0 (not 1 as you said in your question)The graph of the function f(x) = 3 sin x 4 cos x is a sine wave that has been translated Calculate by how many degrees and in which direction the wave has been translated f(x) = 3 sin x 4 cos x = 5 sin (x v) v = tan −1 (4 / 3) ≈ 531° The wave has been translated by 531° to the left (f(x) ≈ 5 sin (x 531°) Example 3 The graph of y=sin(x) is like a wave that forever oscillates between 1 and 1, in a shape that repeats itself every 2π units Specifically, this means that the domain of sin(x) is all real numbers, and the range is 1,1 See how we find the graph of y=sin(x) using the unitcircle definition of sin(x)
