    smart choice, sorry i cant help better :/ all i know is that sec is 1/cos and cos is cos over 1 so technically they would cancel each other out..

    sec x = 1/ cos x .....so. cos x =1/sec x also sec x /(1/sec x ) = sec^2 x and (1/cos x)/cos x = 1/cos^2 x so, it can be written as sec^2 x or 1/cos^2 x but not cos^2 x i know it doesn't affect your score now, but i wanted you to know the standard relation, sec x=1/cos x
