Question

1. Looking at the graphs of $y = \cos(\theta)$ and $y = \sin(\theta)$, at what values of $\theta$ do $\cos(\theta) = \sin(\theta)$? Where on the unit circle do these points correspond to? 2. For each of these equations, first predict what the graph looks like, and then check your prediction using technology. 1. $y = \cos(\theta) + \sin(\theta)$ 2. $y = \cos^2(\theta)$ 3. $y = \sin^2(\theta)$ 4. $y = \cos^2(\theta) + \sin^2(\theta)$

Step 1

To find the values of θ where cos(θ) = sin(θ), we can set the two equations equal to each other and solve for θ: cos(θ) = sin(θ) cos(θ) - sin(θ) = 0 Using trigonometric identities, we can rewrite this equation as: √(2) * (cos(θ) - sin(θ)) = 0 Now, we have two Show more…

Looking at the graphs of y=cos and y=sin, at what values of Î¸ does cos(Î¸) = sin(Î¸)? Where on the unit circle do these points correspond to? 2. For each of these equations, first predict what the graph looks like, and then check your prediction using technology: 1. y = cos(0) + sin(Î¸) 2. y = cos(Î¸) 3. y = sin(Î¸) 4. y = cos(Î¸) + sin(Î¸)
