The height h of the top of a pylon is calculated by measuring its angle of elevation
Question:
The height h of the top of a pylon is calculated by measuring its angle of elevation α at a point a distance s horizontally from the base of the pylon. Find the error in h due to small errors in s and α. If s and α are taken as 20 m and 30° respectively when the correct values are 19.8 m and 30.2°, find the error and the relative error in the calculated height.

I have been teaching college students in various subjects for 9 years now. Besides, I have been tutoring online with several tutoring companies from 2010 to date. The 9 years of experience as a tutor has enabled me to develop multiple tutoring skills and see thousands of students excel in their education and in life after school which gives me much pleasure. I have assisted students in essay writing and in doing academic research and this has helped me be well versed with the various writing styles such as APA, MLA, Chicago/ Turabian, Harvard. I am always ready to handle work at any hour and in any way as students specify. In my tutoring journey, excellence has always been my guiding standard.
