Question

ok guys i need help.... how do you do verify this trig identity? cscx (cscx-sinx) + (sinx-cosx)/sinx + cotx = csc squared x

Answer 1

split that 2nd fraction into -cotx+cotx=0

Answer 2

ok...

Answer 3

i mean do you see that 2nd fraction beomces 1-cotx and after that we see +cotx

Answer 4

wait where did you get the zero?

Answer 5

ok yah haha

Answer 6

thank you for helping me :)

Answer 7

is that all you needed?

Answer 8

after that would what would i do with my cscx (cscx-sinx)?

Answer 9

I got 1/sinx-sinx+1=(1-[sinx]^2+sinx)/sinx=([cosx]^2+sinx)/sinx=[cotx]^2+1=(cscx)^2

Answer 10

oops

Answer 11

cool cool thank you so much is there a way to reward you or something by making me your fan or something?.... what?

Answer 12

fan but I made a mistake

Answer 13

how do i make fan.... and let me look at it ...

Answer 14

do you see become a fan by my name?

Answer 15

nope nothing is by your name

Answer 16

no worries lets just find my mistake

Answer 17

ok

Answer 18

what did you do with the cscx tht was factored out?

Answer 19

1/sinx-sinx+1 (here I found a common denominator) 1/sinx-(sinx)^2/sinx+sinx/sinx

Answer 20

so we have (1-(sinx)^2+sinx)/sinx

Answer 21

ok cool ..... is that all over sinx or just the sin^2 x +sinx?

Answer 22

so we have ([cosx]^2+sinx)/sinx=[cosx]^2/sinx+sinx/sinx=(cosx)^2/sinx+1 BUT (cotx)^2+1=(cscx)^2. IS something missing from your question?

Answer 23

my problem is cscx(cscx-sinx) + (sinx-cosx/sinx) +cotx = csc^2x

Answer 24

so i think thats right ...

Answer 25

omg im stupid i got it let me attach it

Answer 26

it looks right except idk where you got the cos lol

Answer 27

i dont know either

Answer 28

and we could had done -1+1

Answer 29

I made it way more difficult than it should had been sorry

Answer 30

ok cool thanks i found the become a fan button

Answer 31

and hey it worked out didnt it :P thanks a ton :)
