just revise it over and over in your head! There is no real way to remember it other than to just keep revising!
Trigonometry is used in design of everything from buildings to instruments to appliances. It is also used in electronics, acoustics, EM radiation, flight, navigation, projectile motion, and nearly every every application of waves and forces in physics and engineering.
Depending on your career, you may or may not need trigonometry. If your job does not require a lot of math, it is unlikely that you will use trigonometry very often, however, this is not a reason not to study it. The skills and discipline developed in your trigoometry class will help you no matter what career you choose.
Suppose you want to get from your house, located on the south-west corner of a field (rectangular shaped), to your friend's house, located in the north-east corner of the field. You can follow a road 4 miles East then 5 miles North for a total of 9 miles. You want to know how far it would be to get to your friend's house if you walked across the field. By pythagoras's theorem you know the distance from your house to your friend's house is sqrt(4^2+5^2)=6 miles. So going across the field saves 3 miles. that's your answer please ask another question we know everything
People who wanted to apply complex Algebra to real world concepts, like equations of a slope on a bridge founded analytic geometry.
While doing your homework, or on mapping, or for distance.
it can be used when adding up the sides of a computer toaster
You work as a house painter. When you set up your ladder, you like to set the base 5-ft from the wall, for stability. How high on the wall can you reach with a 12-ft ladder ? With a 15-ft ladder ? With a 30-ft ladder ? ============================================================== The question is not: Can the Pythagorean Theorem help you in real life ? The question is: Is your life real enough yet that you can use the Pythagorean Theorem to make it easier ?
In real life its not useful, unless you're going to need geometry in the career you choose.
The distance from home plate to first base is 90 feet and the distance from first base to second base is also 90 feet making a right angle; you can calculate how far the catcher needs to throw to 2nd base from home by Pythagorean theorem. Answer is 127.3 feet
