First, let me make sure I understand the problems.
Is (1) ?
Is (2) ?
HELP! I'm in Math 12 and have a unit exam soon; the questions on my review all seem to be ones I don't have in my notes and can't understand. A couple I've been struggling with for an hour. Can anyone explain how to do these?
1. sec(-1)-sec(-x)sin*squared*x
So far, I got to:
=sec-1+secxsin*squared*x
=___1____ -1 + __1sin*squared*x__
cosx ************* cosx
=___1___ - __sin*squared*x__
cosx ************* cosx
= __1-cos*squared*x__
cosx
...and now I'm stuck! What went wrong?
2. __cos*squared*x__
cot*squared*x
=___-cos*squared*x__
cos *squared*x
= 1
...and, um, that's it. Thx!!!
Hi there!
Um, sort of... 1. sec(-x)-sec(-x)sin*squared*x
2. cos*squared*(-x)
over
cot*squared*x
(sorry, havn't figured out how to get a square in there yet)
What's going on with thoses pesky brackets? How do they work into the equation properly?
THX!!
