Learn to write the three trigonometric function ratios from a triangle

The video tutorial explains how to find and write the trigonometric ratios for angle R in a triangle. It covers identifying the hypotenuse, adjacent, and opposite sides relative to angle R. The tutorial then demonstrates calculating the sine, cosine, and tangent ratios using these sides. Finally, it discusses simplifying these ratios and using calculators for calculations.

Describe the relationship between the sides of the triangle and the cosine ratio for angle R.

How do you find the tangent ratio for angle R?
