Trigonometric Identities - I have a attachment of 2 problems of which I am trying to solve. For both of these problem, I am to derive an expression.
Derive a Trigonometric expression.
Please see attached.
Simplify Seven Trigonometric Expressions - 1. [sin(x+b) + cos(x+b)]/[cos(x+b)-sin(x+b)]=
2. cos^2(x+b)-cos^2(x-b)=
3. tan x + cot 2x =
4. tan (45 + x) -tan (45 -x)=
5. tanx - cotx + cot 2x =
Plus two more...
