The first activity involves performing some calculations and creating the graph of the cosine function in Excel: y(t)= A cos (wt + φ0)
Steps:
- First, I provided values for time (t) and then multiplied it by W to obtain wt. I added φ0 to the result.
- Then, I calculated the radians and cosine of the angle obtained.
- Finally, I multiplied the cosine value obtained by the A value and created the graph with these numbers.
The graph obtained is:
