සයින් කොස් ටෑන් - 10-06-2017, 07:22 AM

ඉස්සෙල්ල කියන්ඩ ඕන මම උසස් පෙළ ගණිතයට එච්චර දක්ෂයෙක් නෙමේ..
ඒ වුණාට සාමාන්‍ය පෙළ ගණිතයට මට D එකක් තියෙනව
කොහොමහරි අමාරුවෙන් හරි උසස් පෙළ ගණිතය තේරුම් ගන්ඩ ආසයි..

උදා- සාමාන්‍ය පෙළ අපිට සයින් කොස් ටෑන් ඉගැන්නුවෙ සෘජු කෝණික ත්‍රිකෝණයක් අරගෙනනෙ..

එතකොට අංශක 0 ඉඳං 90ට එනකං විතරයි සයින් කොස් ටෑන් අගයන් තියෙන්නෙ..
ඒත් ඒලෙවල් වලදි ඕනම අංශක ගාණකට සයින් කොස් ටෑන් අගයන් තියෙනව
0-360ට එනකං...

ඒ වුණාට අපිට මහා කෝණික ත්‍රිකෝණයක් අරං සම්මුඛ පාද බද්ධ පාද බෙදල ඒ අගයන් ගන්ඩ බෑ
අංශක 90ට වඩා ගන්ඩනං මහා කෝණික ත්‍රිකෝණයක් ගන්ඩ වෙනවනෙ..

බලං යනකොට මෙතන ඇත්තටම තියෙන්නෙ ඛණ්ඩාංක තලයක්
සම්මුඛ පාද බද්ධ පාද කර්ණය නෙමේ...
Y අක්ෂය, X අක්ෂය තමා මෙතනදි සලකන්නෙ..

තව දෙයක් තමා මාපාංක. ඕලෙවල් වල මාපාංකයක් ගැන කියන්නෙ නෑනෙ..
