Answer 3

derivative of (2x-1)^2 = 2(2x-1)*2
derivative of tan(2x-1)^2 = sec^2 (2x-1)^2
use "chain rule"

Answer 4

not product?

Answer 5

just multiply of them, gives
y' = 2(2x-1)*2* sec^2 (2x-1)^2
y' = 4(2x-1)* sec^2 (2x-1)^2
y' = (8x-4)*sec^2 (2x-1)^2

Answer 6

I thought it was sec2(8-4)

Answer 7

sec 2 from tan and then (2x-1)^2 for second part which is chain

Answer 8

multiplying process all derivative parts, its called chain rule
