Hello I needed help with cos and sin. I failed my chapter test and I need to correct it on a blank piece of paper and make a new scantron. I needed help with all the questions on the test I uploaded. I only answered the first two questions when I took the test last Friday.. I would of did better you know My brother passed away and I just been going through the motions and try my best to focus on the test is kinda hard with my mom and all idk. I have been going over the review packet some more sine its the same just diffrent numbers. Can you show me how to do the problems It doesn't have to be in detail. Much Appreciated, Thank You.
