Trigonometry is like a special branch of
math that deals with triangles and angles.
It's super useful for understanding and
solving problems related to things like
waves, engineering, and even astronomy.

It's super useful for understanding and

What is Trigonometry?
At the heart of trigonometry are three main
functions: sine, cosine, and tangent, often
abbreviated as sin, cos, and tan. These functions
help us figure out the relationships between the
angles and sides of a triangle. For example, if you
know the length of one side and an angle in a right
triangle, you can use trigonometry to find the
lengths of the other sides.

What is Trigonometry?
It is the ratios of two sides of a
right angle triangle.
Suppose we have a right-angled
triangle ABC.
Thus the trigonometric Ratios are
defined as the largest side of a
right angle triangle is known as
hypotenuse.
