## Aurovidya Conference

Our trip to Hyderabad for Aurovidya Conference has been canceled at the last minute due to COVID. They have asked us to attend a 1-hour session where all the participants gave a brief on their session what they have planned to deliver in the offline session. There were about 140 participants who attended the session. Pratap, Poovizhi, and Prabha gave a short presentation that we planned to do it offline with the people.  It was interesting to present our work with others and others also presented on integral education. The presentation on Self-awareness through STEM was well received.

A reflection received after the presentation from Chhalamayi
Reshma “I Would like to thank you for willingly and graciously participating in the Curtain Raiser of the AuroVidya Seminar.
We could get an inspirational glimpse of your presentation/session.
We very much look forward to you attending the Seminar offline soon.”

## Real-Life Example of Trigonometry

A man is standing near a Hot air balloon. He looks up at the Hot air balloon and wonders “Height of the Hot air balloon?” The height of the Hot air balloon can be found without actually measuring it. What we have here is a right-angled triangle, i.e., a triangle with one of the angles equal to 90 degrees. Trigonometric formulas can be applied to calculate the height of the Hot air balloon if the distance between the Hot air balloon and man, and the angle formed when the Hot air balloon is viewed from the ground is given

It is determined using the tangent function, such as tan of angle is equal to the ratio of the height of the Hot air balloon and the distance. Let us say the angle is θ, then

tan θ = Height/Distance between object & Hot air balloon.
Distance = Height/tan θ

Let us assume that distance is 30m and the angle formed is 45 degrees, then

Height = 30/tan 45°
Since, tan 45° = 1
So, Height = 30 m

The height of the Hot air balloon can be found out by using basic trigonometry formulas.
