Homework Statement I've got the equation of a parabola y=2x^2-4x+1 with point (-1,7) and a tangent line running through it the point. I'm supposed to find the equation of the line. Simultaneously solve this equation with that of the parabola, place the results in form ax^2+bx+c, and find the...

All I knew is this. arcsin(sin.1879474972t-π/2)=1879474972t-π/2 Did I do something wrong or what should I do?

Thank you, turns out I was on the right track. Here's what I did. -23=100sin(.1879474972t-π/2) -.23=sin.1879474972t-π/2 -.2320776829=.1879474972t-π/2 t=7.123 Now the problem is I'm not sure how to find the second time.

Homework Statement A Ferris wheel of radius 100 feet is rotating at a constant angular speed ω rad/sec counterclockwise. Using a stopwatch, the rider finds it takes 5 seconds to go from the lowest point on the ride to a point Q, which is level with the top of a 44 ft pole. Assume the lowest...

Hi everyone, thank you for the input. Let me clarify my situation, I uploaded a diagram; the approach I had been working on was the one Mandelbroth had mentioned. I had y = mx-m3+2 and y^2 + x^2 = 1, when I plugged the first equation into the second I wasn't sure what to do especially because...

Hi I'm trying to study over break, this isn't an exact quote but its the part of the problem I need help with. Thanks. Homework Statement Draw the unit circle and plot the point P=(3,2). Observe there are TWO lines tangent to the circle passing through the point P. Lines L1 and L2 are...
