Hi. I seem to have some trouble when an equation with tan surfaces. If someone could help me it would be great. want to know if i actually even started correctly.
1) suppose tan x = -4/3 with 0 < x < pi. Find the exact value of tan (x + pi)
If i start this with the sum/difference identity of tan (x + pi) = tan(x) + tan (pi) / 1 - tan(x) tan (pi)
Then this should get me through to the answer right?
I hope.
2) suppose tan x = -4/3 with 0 < x < pi. Find the exact value of cot x.
Ok for this one I chose a double angle identity but the more i looked at my steps and solution the more i doubted it. Suffice to say i erased that answer.
Any help would be appreciated.
Thank you
