What is Sin θ? | Tamil | Part 1 | Adhirathan.

HI BRO , BIG FAN .

Hi Quality Engineer, Good question. I don't have a straight forward answer for this and I guess nobody will. You can intuitively find the importance of angle 0 and 90 as the former is perfectly horizontal and later is perfectly vertical(if you consider the ground as reference). angle 45 is the midpoint between 0 and 90. I assume that you are clear about these three angles and questioning the significance of angle 30 and 60. Let me explain that As an angle 30 didn't seem to be of much importance but when you consider real world scenario many beautiful things happens at 30 degree. Let me explain you with an example. consider a room with lights on ceiling and right side wall. you are having a stick of length 1m. Now you can see the shadow of the stick on left side wall and floor because of the lights. if you hold the stick vertically then the shadow on the reft wall would be of length 1m and floor would be zero(or width of the stick). Now start rotating your stick to make it horizontal. now shadow on the left wall will start to shrink and shadow on the floor will start to grow. The shadow on the left wall is the sin theta of the angle in which you are holding the stick. The shadow on the floor is cos theta. now measure the angle of your stick when the shadow on the left wall has the length exactly equal to half of the length of the stick(1/2m). you will get 30 degree. If you do the same for shadow on the floor you will get 60 degree. I know this is an awful and long scenario, don't worry If you didn't get it I will try to post this explanation in an animated format as shorts soon. Thank you for asking. _p_hoton.

Thanks for ur reply , not clarrified for 30 and 60 degree

@@AdhiRathan sir,..I got clearly,..now my doubt is wherever we should take sin? Cos? Tan? What is the difference between those ,..🙏
