The height above the ground of a rider on a Ferris wheel can be modelled by the sine function h(x) = 25

Question

The height above the ground of a rider on a Ferris wheel can be modelled by the sine function h(x) = 25

sin(x – 90°) + 27, where h(x) is the height, in metres, and x is the angle, in degrees, that the radius to the rider makes with the horizontal. Show on the table for one revolution of the Ferris wheel as follows:

Then predict and explain the values for a second revolution of the Ferris wheel.

Question

Using the Sine rule calculate the horizontal and

vertical component forces. Then use any trigonometric calculation to find the resuant force ‘R’ and the angle at which it acts relative to the horizontal ‘r’

I find vectors impossible to understand, I don’t even know how to approach this problem. Is there any simple way of understanding this?

Question

Please show the step by step on how to solve it. Thank you.

  1. The Capital Wheel at the National Harbor is

a Ferris wheel with a diameter of 165 feet. If it were to spin at a rate of 2.1 revolutions per minute, what is the linear speed of a point on the outer edge of the wheel, in miles per hour?

  • Find the exact values of the remaining 5 circular functions (cosine, tangent, cotangent, secant, and cosecant) for angle θ, given that cosθ = 4/7 and θ is an angle in the 4th quadrant. Find exact answers, and simplify them.
  • Solve, finding ALL solutions. Express your answer exactly, using radians. Show work.

    Question

    See attached questions and answers below from my grade 12 advanced functions text which includes trigonometry. I

    understand the question and answer. For future problems, I know that it’s a good idea to break down given angles, i.e., cos (15) into the remarkable or known angles that are associated with a triangle and then apply the compound angle formulas.

    Can someone please provide a list of the remarkable (or most often used in grade 12 Trig) angles please? Please give the angle values in degrees and radians. I searched google but too many hits came up!

    If you can provide the name of the triangle the angles are from, that would be greatly appreciated too!
