Must be in R programming

2.1 Use R to define a data sequence t-seq (2015, 2018, length 100), and then plot the following two functions on the same figure: ysin(2(t-0.1) and y- cos (2mt). Hint 1: For the problems in this chapter, you can use R to compile both your R programs and results, including figures and tables, into a pdf file or MS WORD file. In your RStudio window, click File and choose Compile Report.. You have freedom to choose the report output as a pdf WORD, of HTML file. Hint 2: Another way to put your results together is to use copy and paste to generate a WORD file
