what is the answer fot that? or thats just a final answer?

3. Grazes

Depends. What is the objective here?

4. starbot

cotx=1/tanx tanx+1/tanx tanx/tanx =1

5. micabar2696

i got a question that is sinx/cosx+cosx/sinx

6. Grazes

Dude... tanx+1/tanx does not equal tanx/tanx

7. Grazes

Then yes, tanx+cotx is the answer.

8. micabar2696

and 1/tanx+cotx?

9. Grazes

Are you deriving that from tanx+cotx? O_o

10. micabar2696

no! is another question using that same number

ok, so first you change the equation in terms of Sinx and cosx so because tanx= sinx/cosx and cotx= cosx/sinx you're left with (sinx/cosx)+(cosx/sinx) now add them as you would any other fraction. ( Make sure to make them have common denominators before adding)

12. Grazes

did i? i have no idea

do you want me to explain to you or just give you the answer?

15. Grazes

He has the answer already. I'm not sure what he wants anymore...

16. micabar2696

thats not simplified, the answer is SecxCscx

18. Grazes

oh. For 1/tanx+cotx, it would be 2cotx because cotx+cotx=2cotx

gosh that was difficult to write

btw i tried the best i could with my mouse...don't judge my handwriting

it's ok @starbot i kinda forgot about trig identities too since i took it during first quarter :/
