So you can actually use a couple trig identities
tan(x-a) =(tan x-tan a)/(1+tan x*tan a)
From there, easy!
(tan x-tan a)/(tan x-tan a)/(1+tan x*tan a)
1/1/(1+tan x*tan a)
which is
(1+tanx*tana)
1+tan^2a
sec^2 a
typo, forgot the 1/1
Its $13.79..... hopefully it helps
I think the answer ia A that what i think
(9x 10^-3)^2=, so d 8.1x10^-6
Evaluate 1/2a^-4b^2 for a =-2 and b=4
A number raised to a negative exponent is sometimes negative.
Hope this helps, now you know the answer and how to do it. HAVE A BLESSED AND WONDERFUL DAY! As well as a great Valentines Day! :-)
