7. The number of visible sun spots varies rhythmically from 10 to 110 per year over a period of eleven years. The 110 max last occurred in the year 2014. a.) b.) Write a sinusoidal function N (t) to model that number of sun spots per year, where t is in years past the year 2014. What number of sun spots does your function predict for the year 2018?

The height of a wave can be represented by the function y = 3 cos (pi/8 * (x - 6)) + 4 with time in What are the maximum and heights, and when do on the interval 0 < z < 24

Find f), (b) f(r) tan(2r)

Graph the function f(x) = cos(x) + sin(x) by first graphing y = cos x and y = sin x on the same axes then pick a selection of x values and add their values together to get y values for f(x).  When you've got enough points to see the trend of the graph, connect them to get the final result.
