Trigonometry - 8. Trigonometric ratios for angle 45 degrees

Hi Friends,
This is the eighth webisode of this series where we are learning about "Trigonometry". So far in this series, we have learned what are the six trigonometric ratios of an acute angle (in right triangle) and how to solve questions involving trigonometric ratio questions.
In this video, we learn how to find out the values of trigonometric ratios of 45 degrees.

This video is for class-10 (class-X) students.

Cheers,
Friends at Risingpearl.
