ELI5: solving with the trigonometric ratios
// explanation
What are trigonometric ratios?
Trigonometric ratios are special fractions that compare the sides of a right triangle [2]. They help you find missing sides or angles when you know some information about the triangle.
What are the main ratios?
The three main ratios are sine (sin), cosine (cos), and tangent (tan) [8]. Each one compares different sides of the triangle in a specific way.
How do you use them to solve problems?
You pick the ratio that matches what you know and what you're trying to find, then use it like a recipe [2]. If you know an angle and one side, the ratio helps you find another side.
What if you need to find an angle instead?
You can use the inverse of these ratios to work backwards from the sides to find the angle [2]. It's like using the ratio in reverse to discover the missing angle.
