100

Tan on the unit circle

sin/cos

200

5pi/4 in degree form

225 degrees

300

315 degrees in radian form

7pi/4

somewhat simple

100

sin^2+cos^2

1

200

cos(x)/sin(x)

cot(0)

300

1-sinx/1+sinx

(sec^2-tan^2)^2

Not as hard as quadratic equations

100

cos(x)=1/2

300,60

200

2cos(x)+1=0

2pi/3 or 4pi/3

300

5cos(x)-sr3=3cos(x)

pi/6, 11pi/6

idk what to do half the time

100

csc^2(x)-4=0

30,150,210,330

200

sin(x)^2+3sin(x)-4=0

90

300

cos^2(x)+9cos(x)+18=0

no solution

A Ferris wheel has a diameter of 80 ft, and it is standing 5 feet above the ground. The center of the circle is 45 ft above the ground. It takes a total of 90 seconds to fully spin around in a full circle. Find the maximum point he can reach.

(80, 90)

Using the same problem from above how long would it take for the wheel to spin 1/5 of the way around.

18 sec
