Question

Given that sin x = p, find an expression, in terms of p, for sec2 x.

Answer 1

its sec^2 x
or
sec (2x)
?

Answer 2

if it is sec^2 x
then first find
cos x from sin x

then sec x is just 1/cos x

Answer 3

can you show me how it works ;; A ;; i just can't get rid of the sinx

Answer 4

sin x = p
sin^2 x = p^2

cos^2 x = 1 - sin^2x
cos^2x = 1 - p^2

sec^2x = 1 / cos^2x = = 1 / ( 1 - p^2)

Answer 5

I've assumed you want sec^2 x not sec(2x)
