Now, let's meet the trigonometric ratios: sine, cosine, and tangent. They're like detectives, helping us find out measures of angles and sides in right-angled triangles.
**
**
The names 'sine', 'cosine', and 'tangent' come from the Latin words for 'sinus' (bay), 'cosinus' (adjacent), and 'tangens' (touching). They were first defined by the Greek mathematician Hippocrates around 150 BC, but it was the Indian mathematician Aryabhata who popularized their use in trigonometry around 500 AD.
**
**
Now, let's put these ratios to work in right-angled triangles. Remember, in a right-angled triangle, one angle is always 90 degrees, like the corner of a wall.
Let's say you're building a HDB flat and need to find the length of a wall (side 'b') that forms a 37-degree angle with the floor. If the height of the wall (side 'a') is 2.8 meters, you can use the sine ratio:
sin(37°) = b / a
Solving for 'b', you'd find the length of the wall. Isn't that shiok?
Sine and cosine functions are fundamental in trigonometry, but they often cause confusion. Remember, sine is the ratio of the opposite side to the hypotenuse, while cosine is the adjacent side to the hypotenuse.
In trigonometry, angles are measured in degrees or radians. It's crucial to know which measure your problem requires. Using the wrong measure can lead to incorrect results.
Special angles like 30°, 45°, and 60° have specific trigonometric values that can help simplify calculations. However, using these values inaccurately, such as mixing up the sine and cosine values, can lead to errors.
