Where trigonometry starts

That even the name is complicated

It shouldn't be that easy no

It starts in triangle, not acute or obtuse

It is in the right triangle.

And this triangle has a scheme

To solve any problem

Pythagoras is the theorem…

"*The squared measure of the larger side called the hypotenuseEquals the sum of the square of the smaller sides*"

Who doesn't know learn

Who knows already uses.

The sine of x is the opposite collet

about hypotenuse

The cosine of x is the adjacent collet on the hypotenuse.

And what is the tangent?

It is the opposite collet over the adjacent…

And then come to the circle

learn from us…

Secant, cosecant and the cotangent

And learn math in a different way…
