All these ratios people are having trouble with today.

Its pretty easy once you get the hang of it.

So they release 12 grizzly.

We can say 12/x since we dont know the amount of grizzly bears in total.

We can then set 12/x equal to 2/21 and solve for x by using cross multiplication

What are the graphs of y=sinx and y=cosx in the interval from -2 pi to 2 pi?
g100num [7]
I used Excel to create the tables and the graphs.

I attached both the tables and the graphs.


You should replace the numbers of the x-axis (in both graphs) by the numbers as a fraction of pi. Those numbers are also included in the table, so you should not have problems with that.
