|
| Well good luck next time but on that next test I might put Trigonometric Identites on there so be prepared this time. | |

| Hello? Hey Dave we need to study right now on the Sum and Differences for Cos Function. Professortold me and only we know. | |
|
| Hey Lue,so you saying like right now..Hmm now you want to study. First answer this old question. Find the coterminal angle of 32 degrees? | |
|
|
|
|
|
|
| That would be 32+360=392 and 32-360=-328. So lets stop playing around and Find cos 15 degrees on sum and difference identities. | |
|
| WOW! That was impressive still remember I see but that would be radical 6 + radical 2 over 4 and just do the same and get a negative. Good work for today see you tomorrow. | |
