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

What is an easy way to remember Pythagoras theorem?
h^(2) = a^(2) + b^(2). In words, 'The hypotenuse square is equal to the sum of the squares other two sides'.
How is trigonometry used in real life?
Trigonometry is used in the fields of design, music, navigation, cartography, manufacturing, physics, optics, projectile motion, and any other field which involves angles, fields, waves, harmonics, and vectors.
Application of trignometry in real life?
If you work in engineering, you'll need trigonometry, and other advanced math topics, all the time. Otherwise, you can come along quite well without it, and will seldom find any practical use for it.
What is an ellipse?
A real-life example of an ellipse is the path that some heavenly bodies travel in space. Earth's path around the sun is elliptical.Informally, a flattened circle. You can read the Wikipedia article for a more formal definition, as well as to investigate its different properties.
What are the real life examples for trigonometry?
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.
