Prove that cos x/1-sin x - cos x/1+sin x = 2 tan x is an identity. pls show work

answer: two angles are called supplementary if they add up to 180°. example: the two angles (140° and 40°) are supplementary because they add up to 180°.

step-by-step explanation:

hello from mrbilldoesmath!

answer:   x^2 + y^2 = 1024

discussion:

the equation of a circle with center (h,k) and radius "r" is

(x-h)^2 + (y-k)^2 = r^2.

in our case

(x-0)^2 + (y-0) ^2 = 32^2 = 1024

you,

mrb

thus, the first answer choice, y = sec x, is the correct one

i would say true? if the unit was informational and it "refreshed your understanding", then true.
