Thats my reasoning, Answer is DYes. Tan is negative in quadrant 2 and 4.
Working angle is pi/6 (30 degrees)
1-1/6 = 5/6
2-1/6 = 11/6
thus, its 5pi/6 ad 11pi/6 ---> D
B? It was a tossup between A and B for meWhat did u guys put for the derivative graph?
It was a, since straight after the point a would be a max-tp which means concave down which means f''(a)<0.B? It was a tossup between A and B for me
I put A not 100% sure though...B? It was a tossup between A and B for me
B? It was a tossup between A and B for me
Yeah pretty sure it's 4a...that's what I gotIt is f'(x) > 0 and f''(x) < 0
Yeah, I got that.It is f'(x) > 0 and f''(x) < 0
niceYeah, I got that.
Its increasing so f'(x) > 0 then it was a concave down point so f''(x) < 0
Yep 8 is AI got A for 8, everything else is the same.
