We know enough about trigonometry.. or do we?????
Here are some real life situations where we just need to apply trigonometry.
Ready for the challenge????
Here we go!!!
? I am standing somewhere between two buildings of equal height.
Ive to
tilt my head more, to look at the top of the first building as compared to
that of the second.
So can you tell me to which building am I closer???
Always remember greater the angle of elevation closer were to the object.
Next one is a bit easy, Im sure you can answer.
? Now this time the angles made from my eyes to the top of both the
buildings are equal.
To which building am I closer now??
? Alright but can you guess the measurement of these angles??
Lets look at things from a different perspective.
? Im on the top of a building looking down at two cars on the road at an
angle of 350 and 770.
Which car then should be placed nearest to the building??
Angle of elevation = angle of depression.
Lets have a view from my house which is on the second floor.
? Im looking at my friend who is on the seventh floor of the opposite
building at an angle of 650.
So at what angle would my friend look back at me??
The reason is same as before.
I am bored now, lets go out of the bulding.
? Im at a 70ft distance from a 70ft building, the angle made from my eyes
to the top of the building is 450.
Suppose the height of the building is
doubled then to maintain the same angle, how much distance must I travel
back?
Last one lets try to solve this with my friend and me.
? My friend is on the top of the building and he threw me a rope which is
90m long making an angle of 300 to the ground.
With this information can you guess the height of the building??
Hope you can see trigonometry in altogether a different way now.
Remember learning math can be fun if you know how to apply it in real life.
