do u mean secant squared?

or secant to the power of 2x-1

**Randy**, Sunday, January 9, 2011 at 3:06pmsecant squared... ((sec^2)x-1)((csc^2)x-1)

**chemistry**, Sunday, January 9, 2011 at 3:08pmre write the question properly

sec^2 x?

is there something there?

there should be either x or thetha there

and is it multplied

**Randy**, Sunday, January 9, 2011 at 3:09pmSorry forgot the =1 on the end, ((sec^2)x-1)((csc^2)x-1)=1

**helper**, Sunday, January 9, 2011 at 3:22pm(sec^2 (x) - 1)(csc^2 (x) - 1) = 1

sec^2 (x) - 1 = tan^2 (x)

csc^2 (x) - 1 = cot^2 (x)

(tan^2 (x) )(cot^2 (x)) = 1

cot^2 (x) = 1/tan^2 (x)

(tan^2 (x) )(1/tan^2 (x))= 1

tan^2 (x)/tan^2 (x)= 1

1 = 1
