Answer:
Below.
Step-by-step explanation:
- tan 2x = -2tanx / (1 - tan^2x)
Using the identity tan^2x = sec^2x - 1 and substituting for tan^2x:
- tan 2x = -2 tanx / (1 - (sec^2x - 1))
= 2 tanx / ( - 1(sec^2x + 2))
= 2 tan x / (sec^2 x - 2)
I got 5.5 but I could for sure be wrong :/
Answer:
2^5 or 32
Step-by-step explanation:
Answer:
r=-4
make r the subject and solve
X+4=-4
3x-8=-8
Hope it helps.
