Hello, daviskane!
Do you know any of the basic identities?
Verify the following trigonometric identities and show all steps.
The left side is: .
.
and we have: .
1. verify the following trigonometric identities and show all steps
let @=theta
1. cos^3@+sin^2@cos@=cos
2. cot@
---- = tan@
csc^2@-1
3. cot@csc@tan^2@=sec@
4. sin@ (1 + csc@)=sin@+1
5. cos@=sec@ - sin@tan@
6. 1+cos@ = cot@(sin@+tan@)
Answering any part of these would help a ton! Thanks.
