As we learned the 6 trigonometric ratios of 45 degree angle , in the same way now we will find the 6 trigonometric ratios of 30 degree angle. But we will find out this value combining the 60 degree in the same figure.
You might be saying if we know the value that’ enough but please try to understand the concept behind it !
So Ready for study ! Did you take you pen & notebook. Command your mind that your are understanding very nice
trigonometry. And in this lesson also you are going to understand very nicely !
Lets begin !
Well how was it ? Can you try it once, yourself ? Yeah You can do..so please try to do some practice to find the trigonometric ratios of 30 degree and then we will learn how to find the trigonometric ratios of 60 degree.
