i don't understand how you solve these, can somebody please help me and explain how you do them!!
questions i) 4sin^3 x answers i) 12cosxsin^2 x
ii) xe^x ii) (x+1)e^x
iii) sinx/x^2 +1 iii) (X^2+1)x cosX - sinX x 2X / (X^2+1)^2
iv) ln(2x^2 +8) iv) 4X / 2X^2 +8
Really stuck!!!
WOuld appreciate the help!
