Question

Identify an everyday item or situation that could be modeled by a trigonometric equation/graph.
Which trigonometric function best models this?
Relate amplitude, period, or other function characteristics to your example.
Consider the domain and the range; explain any restrictions on them.

Answer 1

Answer:

Step-by-step explanation:

Lets consider a situation that the bulb, in your attic is fused...the bulb is attached to one of the walls of the attic...so high you can't get there without a ladder...you bring a ladder to replace the fused bulb with a new working one...suppose the length of the ladder is 5m...now the bulb holder is 5m above the ground and if you want to fix the bulb you would want the holder to be in front of you face...and if you're 1 m tall you would want the ladder to be touching the wall at a height of 4m....so now the question arises at what angle and at what distance should I place the ladder? Well..(refer the image provided) let A be the angle of inclination and x be the distance foot of the ladder is placed from the wall....using sin A you can find the angle of inclination and then using cos A you can find the distance x

(Refer to image for calculations)

So A=53.13°

x= 3m

So here's the scenario...mark brainliest if it helps

Note(this could have been done by Pythagoras theorem and then using cos A you could have caculated the angle)
