If cosecA+sinA=515, the value of
cosec2A+sin2A is m125, m is
Given: cosecA+sinA=515
⇒cosecA+sinA=265
Squaring both sides,
⇒(cosecA+sinA)2=(265)2
⇒cosec2A+sin2A+2=67625
⇒cosec2A+sin2A=62625
⇒cosec2A+sin2A=25125
Hence, m=25.
If Sin A +Cosec A= 2
Then sin2A + cosec2A=__
SinA+cosecA=2;
Find the value of sin²A + cosec²A.
