@IrishBoy123 Quick question

Answer 1

use formula a^2 -b^2 =(a-b)(a+b)

Answer 2

Okay stay here lol i need you

Answer 3

wait your result

Answer 4

How does a and b work we have 4 different expressions..

Answer 5

on numerator let be ,,a" the 1 and ,,b" the cos theta

Answer 6

would it be D??

Answer 7

so using them will get with this above wrote formula = 1-cos^2 theta

yes ?

Answer 8

yes..

Answer 9

idk. please write me here your calculi

Answer 10

in denominator make same with numerator

Answer 11

it was a guess really i have 2 left mins before submiting

Answer 12

Can you do that for me ? i have less than 2 mins and test will close up

Answer 13

1-cos^2 sin^2 +cos^2 -cos^2
-------- = ------------------ = ?
1-sin^2 sin^2 +cos^2 -sin^2

Answer 14

bc. you know that 1=sin^2 +cos^2

yes ?

Answer 15

so it would be D ? Doesn't make sense when i simplify it!

Answer 16

= sin^2 /cos^2 = tan^2

not D. bc. in numerator simplify cos^2 and in denominator simplify the sin^2

Answer 17

So C Thank you so much Jhony
