And what is your Problem pls

what is the 2nd derivative of f(x)=sin(x)cot(x^3)csc(3x^3) and is the graph concave up or concave down? $3 on PS


[/ QUOTE ]

Ok, I can't take it. I'm gonna give this one a shot (and prob fail)

Answer later...

f'(x) = [(sin(x)cot(x^3))' * csc(3x^3)] + [sin(x)cot(x^3) * csc'(3x^3)]

= [sin'(x)cot(x^3) + sin(x)cot'(x^3)]csc(3x^3) + [sin(x)cot(x^3)csc'(3x^3)]

= sin'(x)cot(x^3)csc(3x^3) + sin(x)cot'(x^3)csc(3x^3) + sin(x)cot(x^3)csc'(3x^3)


f''(x) = [(sin'(x)cot(x^3)) * csc'(3x^3)] + [(sin'(x)cot(x^3))' * csc(3x^3)]
+ [(sin(x)cot(x^3)]' * csc(3x^3) + [sin(x)cot(x^3)] * csc'(3x^3)
+ [sin(x)cot(x^3)]' * csc'(3x^3)] + [sin(x)cot(x^3)] * csc''(3x^3)


= [sin'(x)cot(x^3)) * csc'(3x^3)] + [sin''(x)cot(x^3) + sin(x)cot'(x^3)] * csc(3x^3)]
+ [sin(x)cot'(x^3) + sin'(x)cot(x^3)] * csc(3x^3) + sin(x)cot(x^3)csc'(3x^3)
+ [sin(x)cot'(x^3) + sin'(x)cot(x^3)] * csc'(3x^3) + sin(x)cot(x^3)csc''(3x^3)

= sin'(x)cot(x^3)csc'(3x^3) + sin''(x)cot(x^3)csc(3x^3) + sin(x)cot'(x^3)csc(3x^3)
+ sin(x)cot'(x^3)csc(3x^3) + sin'(x)cot(x^3)csc(3x^3) + sin(x)cot(x^3)csc'(3x^3)
+ sin(x)cot'(x^3)csc'(3x^3) + sin'(x)cot(x^3)csc'(3x^3) + sin(x)cot(x^3)csc''(3x^3)


f''(x) = -3cos(x)cot(x^3)csc(x^3)cot(x^3) - sin(x)cot(x^3)csc(3x^3) - 3sin(x)csc^2(x^3)csc(3x^3)
- 3sin(x)csc^2(x^3)csc(3x^3) + cos(x)cot(x^3)csc(3x^3) - 9sin(x)cot(x^3)csc(3x^3)cot(3x^3)
+ 27sin(x)csc^2(x^3)csc(3x^3)cot(3x^3) - 9cos(x)cot(x^3)csc(3x^3)cot(3x^3) + 81sin(x)cot(x^3)csc^2(3x^3)cot^2(3x^3)

YES I SUCK AT LIFE.

NO I DON'T KNOW IF THE CURVE GOES UP OR DOWN BECAUSE I DON'T HAVE MY TI-83 IN FRONT OF ME. SORRY.

THIS WAS TO PREVENT MYSELF FROM GOING ON TILT IN THE SNG'S I'M PLAYING.

Edit: Yes, I probably made many mistakes in that.

Yes, I torture myself.

seems like all the problems of your life have to do something with math ... your all pretty lucky [img]/images/graemlins/laugh.gif[/img]
