Used this for adv functions cuz my teacher decided not to review how to graph basic trig functions, helped a lot

Congrats

Glad i found this video before my upcoming trig test!

Thank you so much, I have a test on this today!

Ferris wheel part b (iii) since the Ferris Wheel is higher of the ground, it changes the min values so there is a change in a and d but not c? (iv) since the graph is inverted doesn't it change the sign of the equation as y= -9.5sin(36x-2.5))+10.7? y = asin(b(x+c))+d

And example number one it looks like to me, is an inverted cosine graph

you made a mistake, in question d), after 7 seconds the riders heigh would be 19.73 meters not 13.66 meters. It verified on desmos
