thanks sammy.. its now 9 am here we nid to pass this by 10am thanks for help... but how about my number 3 and number 4 is that correct? I am not sure what I've done.. especially number 4 with square root thing :)

in number 1 -sin(3x^2+8x-2)(6x+8) then multiply -sin to (6x+8) -(6x+8)sin(3x^2+8x-2) am i correct now guys :)

so my answer in number 1 should be -(6x+8)sin(3x^2+8x-2) and in number to should be 6 tan^2 2x sec^2 2x Am i correct.. or still wrong :)

find the derivatives of differentiation of trigonometric functions 1. y=cos(3x^2+8x-2) 2. y=tan^3 2x 3. y=sin5x sin^5 x 4. y=Square root of 4sin^2x+9cos^2x help here please.. i can't understand trigonometric functions sorry admin or moderator, i just search the net on how...

help plssss.. 2 and 4 please.. I am searching in google.. but i can't get the logic.. im not good in math so please help...

yes. she didn't taught us.. because she will discuss it to us tomorrow.. please help me :)

i don't have any background with that sammy can u help me with number 3 and number 4 please help me.. its our assignment and will be pass tom :)
