To explain: The report on the great trigonometric survey of India.

Explanation of Solution
The great trigonometric survey of India was a fifty year project, that coasted more than a few wars; led to an estimate of the ellipticity of the earth; a key early result in the isotasy and a map of India.
The great trigonometric survey of India started with the measurement of baseline near Madras. Major Lambton selected the flat plains with St. Thomas Mount at the north end and Perumbauk hill at the southern end. The base line was 7.5 mile (21.1Km) long. Lieutenant kater was dispatched to find high vantage points on the hill of the west so as to connect the coastal points of Tellicherry and Cannanore. Between the coasts to coast the distance was 360 miles (580km) and this survey line was completed in the year 1806.
The East India Company estimated 5 years to complete this project of survey, but it took nearly 70 years of time well past the Indian rebellion of 1857 and the end of the company rule India.
The surveyors did not triangulate the whole of India because of the extent of land to be surveyed, but instead created what they called a “gridiron” of triangulation chains running from North to South and East to West. At times the survey party numbered 700 people.

Meanwhile, a firefighter is climbing up the ladder at a rate of 2 feet/sec. When the firefighter has climbed up 6 feet of the ladder, the ladder makes an angle of л/3 with the ground. Answer the two related rates questions below. (Hint: Use two carefully labeled similar right triangles.) (a) If h is the height of the firefighter above the ground, at the instant the angle of the ladder with the ground is л/3, find dh/dt= feet/sec. (b) If w is the horizontal distance from the firefighter to the wall, at the instant the angle of the ladder with the ground is л/3, find dw/dt= feet/sec.arrow_forwardTwo cars start moving from the same point.
