Answer 1

x(21cos3x+6cos3x)+(7sin3x+2cos3x)

Answer 2

that's wrong! it supposed to be -6sin3x.... in the first part

Answer 3

this whole question is wrong because i meant to put differentiate not derivative :/ my bad

Answer 4

ha ha ha!! differentiate and derivative means the samething!!!!

Answer 5

d that is using the chain rule

Answer 7

oh alright thanks
