Find the approximate value of each trigonometric function.
Given that sin0 = 0.312 where - <0 Since 0 lies in Quadrant II, where cos0 <0, cos is approximately

An equation of the line tangent to y=x^3+3x^2+2 at its point of inflection is

The position of a moving particle is given by the position function: f(t)=-9t-t^2-0.2t^3+0.1t^4 a. at what time does the particle reverse direction? b. when is the displacement positive? (round one decimal place and answer in interval notation) c. when is the displacement negative? (round one decimal place and answer in interval notation) d. when is the particle’s acceleration positive? (round one decimal place and answer in interval notation) e. when is the particle’s acceleration negative? (round one decimal place and answer in interval notation)
