pleaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaasw help

can you pleaaaaase help me find the area between y=cos(4x) and y=1-cos(4x) 0<=x<=pi/4
i tried to solve it, and i got like : 2*sqrt3+ pi/12
is it right? if not please tell me how can i solve it...i'm really confused

i found Pi/12
then , i took the integral from 0 to pi/12, and from pi/12 to pi/4
and i got:
integr from 0 to pi/12 cos(4x)-(1-cos(4x) + integ from pi/12 to pi/4 1-cos(4x)-cos(4x)
but i'm not sure if it was right or not...can u check with me please?

    Determine exact value of cos(cos^-1(19 pi)). is this the cos (a+b)= cos a cos b- sina sin b? or is it something different. When plugging it in the calculator, do we enter it with cos and then the (cos^-1(19 pi)).
