You use the identity sin2x + cos2x = 1 (to simplify the expression in parentheses), and convert all functions to sines and cosines. sec x tan x (1 - sin2x) = (1/cos x) (sin x / cos x) (cos2x) = (sin x / cos2x) cos2x = sin x

x = -2/3,7/6

It is: 9-4 = 5

Anything divided by itself equals one.
4 squared minus 2 squared equals 12
x = -2/3,7/6
B squared equals c squared minus a squared then to find B take the square root of you answer for b squared
You have to put your heart into it!
x = plus or minus 6.
square root of 8
