Hello,

Please help me quickly I'm having exam after tomorrow and I have a problem that I can't solve anymore please help me with it

my try for the 1st derivative is :

a.cos(a.sin^-1 (X)).(a)

________________________= Y prime

root ( 1-x^{2 })

I know that I should get The 2nd derivative but as u know it's based on the 1st one so I've to make sure the first one is correct ,,,,, Can Anyone Help ????
