Here ya go. As awlays, find an error, get extra credit.
Looks like I didn't quite finish the last problem (sorry), but I got you far enough. You get the idea...
Also, a couple of you have requested the formulas powerpoint. While this isn't the focus of the test, you may want to look it over.
for #3 wouldn't (1/cos²x)-(sin²x/cos²x)=1 since there is a 1-sin²x which is equal to cos²x, so there whould be cos²x/cos²x which equals one?

ReplyDeleteIt's always, not awlays.
I expect my extra credit.
hey mr. thompson, i think for # 34 and #36, you got the adjacent wrong. I think its supposed to be square root of 85 instead of square root of 65. hopefully i'm right =D

So on numbers 34-36 I didn't get the square root of 65. I got the square root of 85. because 121-36=85. So maybe I am wrong I dont know though. Just wondering.
ReplyDeleteOk not sure if that last comment went through. But on numbers 34-36 I didnt get the square root of 65. I got the square root of 85. Because 121-36=85 which leaves you with the square root of 85. Is that right?

on number 4, is tan2x or
ReplyDelete2tanx/1-tan(squared)x
simplified?
Erik
#44 doesn't sin=1 at pi/2 and
ReplyDelete-1 at 3pi/2 as opposed to
plus or minus root 2 over 2?
Erik
tan2x is fine.
ReplyDeleteaww stupid. i find the extra credit errors but everyone already took the one i was gonna say! (number 34) supposed to be 85 not 65 eh oh well.
