any help with help me....i have a test friday and i stayed after/before skool to get help but my teacher cant teach so im still totally lost
Dude, sorry most of my trig knowledge is gone. The advices I can give you is to look at the formulas they use. All trig problems come down to replacing with formulas to solve. The problem in the text book expect you to practice the formulas of that lesson. Study their examples and you should be able to do the exercises.
And it's math alright. Not the fun kind.
