These can be tricky at first, but you'll get this quickly.

Take note that we are dealing with angles that are integer multiples of .

With little effort, we can see that

Since is an integer multiple of , we can (in essence), ignore it. Thus, what we are asked to find is .

I hope this makes sense!

When we evaluate , we come up with many values. However, we're given a restriction on :Evaluate each for 0<0<2(pi):

So, we see that

Taking into consideration the restriction of , we see that the only possible solutions woud be

I hope this makes sense!

At , we have a horizontal asymptote. Thus, the domain of y would beFind the domain and range:

If we evaluate at large positive and negative values, we see that the function starts to get closer and closer to a value of . Since there was a discontinuity at , we can determine that at , there is a discontinuity as well. Thus, we can claim the range to be

I hope this makes sense!

I'm trying to figure out what you mean by this. Could you state the problem as it is written? I'm sure I'd be able to do this with a little clarification.The other one is a word problem, where as again, i have no clue where to start.

You are given the following vertices of [TRIANGLE]ABC, A(-1,-1), B(3,5), and C (5, -3). State the process to find point of intersection of the median from C to AB and the median form B to AC.

I hope all that I have done so far makes sense. If you have questions, please ask.
