TITLE: TRIGONOMETRY
INTRODUCTION:
If you know the the length and height of a hill, can u find out the slope??????
TASK:
A BOY standing in front of the island office and looking top of the dhiraagu tower. Find the angle of elevation of Dhiraagu tower from the Island Office.
1. Measure the length (From the island office to Dhiraagu tower)
2. Measure the height (Dhiraggu tower)
3. Find out the angle of elevation
TIME:
2 days to finish this project.
PROCESS:
1. Draw a rough diagram to the above question.
RESOURCES:
If you have any quarries from Google search.
CONCLUSION
Now you have learnt and have knowledge about the angle of elevation.

പുതിയൊരു തുടക്കം
എന്നെപ്പറ്റി എന്തു പറയാന്? മനസ്സിന്റെ താളപ്പിഴകള്ക്കിടയില് ഒരു ജന്മം.
വിധിയുടെ കാലചക്രത്തില് നമുക്കു പരിചയപ്പെടാം... ഒരുപാട് സ്നേഹത്തോടെ മാത്രം...
ഞാനും കടന്നു വരികയാണ് ഈ പുതിയ ലോകത്തിലേയ്ക്ക്, ബ്ലോഗുകളുടെ ബ്ലോഗര്മാരുടെ അഭിനവഭൂലോകത്തേയ്ക്ക്...
സ്നേഹപൂര്വ്വം
