Im having a lot of trouble solving the following trig identities:
a) secē x-2 sec x cos x + cosē = tanē x - sinē x
Trigonometric identity: secx cosx=1
secēx-2 sec x cos x + cosē
=secēx + cosē-2
Identity: secēx = 1/cosēx
Use the Identity:
secēx + cosē- 2
Now I am very confused, really unsure on how to prove this identity. I would greatly appreciate any helpful tips.
tanx+1/tanx =1/(sinx cosx )
Identity: 1/tanx = cotx :
Now im completely lost, the R.H.S side is turning out to be "csc x sec x" .
I would greatly appreciate any helpful tips, since I'm very confused here.
