trigonometric ratios of special angles
Hello friends, I am Anil Kore welcome to my channel mathstips4u. In this post I am going to tell you some trick to remember trigonometric ratios of special angles. Special angles are These are most confusing formulas and also difficult to memorize. I shall tell you a simple trick to remember trigonometric ratios of special angles. We draw a following table for sin , cos and for tan Writing numbers 0,1,2,3 and 4 ascending order. Dividing each number by 4. Taking square root of each. In this way we have seen how to remember trigonometric ratios of special angles. In my next post we will learn how to remember trigonometric ratios of quadrant-ale angles.
