I know that trig is use mainly by surveyors, navigators, map makers,etc.
But how can a person like me, who is not a scientist nor professional mathematician to use trigonometry in everyday lives?Please give me some examples of problems where can I use it.(for example in home)
And please explain the solutions.
I just want to know because I found trigonometry to be hard if I didn't know how to apply it.

a)You want to cut down a tree. Based on its shadow and elevation angle you can estimate its height and know where it might fall.
I think that you might be limiting yourself. You might feel that if it cannot be used around the house, what is it good for.
Many other things cannot be used around the house, cranes, operating tables, stop lights, wind generators, but a very useful to every day life.
With out an understanding of trig, you would not get AC power to your house. You personally do not use it, but you are sure glad that the engineers generating the power and getting it to your house do,
Trig is tough, but it's really worth it - lots of things that oscillate (guitar strings, pendulums, and your AC current, as the other guy mentioned) can be represented by sine waves. Once you learn trig, you've got a whole bunch of new things open to you.
If you ever do any do-it-yourself projects, you might find a few uses for trig. Say you're building a gate for a fence, and you want to put some diagonal bracing to keep it square. Before you go buy your wood, you can use geometry (the Pythagorean theorem) to figure out how much wood to buy. Then when you're building the gate, you can use trig to figure out the angle to cut the boards at.

I used to install Wireless Internet at homes, which meant installing equipment on a persons house and pointing it to the tower giving off the signal. I used Trig to determine what angle the antenna must point up or down depending on the height of the tower and the height of where I was installing. We couldn't see the tower, but we would know what direction it was in, its current height above sea level and at which height we where at. Using Trig we calculate the angle of elevation or depression, and adjusted our antennas, because of trig our wireless network was better than others in the same business.

In fact in today's world no body is a surveyor, or a navigator or a map maker.
The application of trigonometry is similar to the application of a band aid. Will you use band aid everyday? No. But when you need it, you best be sure that you have it there or else you'd bleed to death.
