what is trigonometry?
A particular branch of mathematics that deals with angles and their functions
So, what do you think right angle trigonometry is?
So, what do you think right angle trigonometry is?
We can use this to find lengths or angles that are missing in right triangles. These functions are used in geography (distance between two things), astronomy, satellite communications, and more.
What is sohcahtoa?
What is sohcahtoa?
It's a pneumonic device to help you remember the sides that go with each trig function: sine, cosine, and tangent.
For today, we are finding the value of various trig functions using right triangles. If it says sin(x), we read that as "sine of x."
