sweetest angel:
umm ya i got that part its the part where the 1/(cos^2A)^3/2 X cosA is made into 1/cos^2A
isn't it supposed to be 1/cos^-1/2A?

Jan '06 4-b :show did they do the last step??
i got till 1/8cos(arcsin(x/4)) but the next step is magic to me :/

1/(cos^2A)^3/2 X cosA =1/cos^3 A cosA= 1/cos^2 A
