I just cannot express my feelings while watching this video!
I had always thought that trigo would be tough and so I would become afraid asking to my maths teachers to explain me this. But you explained it so clearly in just 10 mins! Deeply appreciate it and may this video reach thousands of students out there facing problems in

please help me !!!!a right angled triangle can have only three possible angles :90 degree and two others whose sum is equal to 90 degree and since trigonometric ratios are valid only for right angled triangle how can we have sin 180, cos 270 etc.
