Hi can you please help me with this question step by step thank you!

#4. Solve the trigonometric equation 6sin2x + Ssinx 3 = 0 on the interval 0 S x 5 2m i Include diagrams (ie. special triangles, etc.) as part of your solution. #5. A Ferris wheel has a diameter of 50 feet. It completes two full revolutions every 40 seconds. (a) Draw a graph representing a person's height above or below the centre of rotation and above the ground. Assume the ground is the reference point with heightO meters. Begin at the lowest point on the Ferris wheel (ie. the person begins the ride at the bottom of the Ferris wheel}. 7 (b) Write 2 equations to represent your graph. One equation must be in terms of sine and the other must be in terms of cosine
