1a. Eliminate the parameter t to rewrite the parametricequation as a Cartesian equation.
| x(t) | = | cos(t) + 1 |
| y(t) | = | 7 sin2(t) |
1b. A dart is thrown upward with an initial velocity of 68 ft/sat an angle of elevation of 52°. Consider the position of the dartat any time t. Neglect air resistance. (Assume tis in seconds.)
Find parametric equations that model the problem situation.
1c.
A dart is thrown upward with an initial velocity of 61 ft/s atan angle of elevation of 56°. Consider the position of the dart atany time t. Neglect air resistance. (Assume t isin seconds. Round your answer to one decimal place.)
At what time will the dart reach maximum height?
t = ?
