Review the equation for a hyperbola in polar coordinates.
#2 Hint: sec^2 = 1 + tan^2
#3
y = 500 sin70° t - 16t^2
Solve for t when y=0 to find the time in flight
The x-velocity is constant at 700 cos70°
So using the time from step 1, distance = speed * time
Please help me set up these problems.
1.) Find an equivalent equation in rectangular coordinates.
r(1 - 2 cos θ) = 1
2.) Find a rectangular equation for the plane curve defined by the parametric equations.
x = sec t, y = tan
3.) A projectile is fired with an initial velocity of 500 feet per second at an angle of 70° with the horizontal. To the nearest 10 feet, find the horizontal distance covered by the projectile.
