Maths Puzzle
the simplified value of 1- (sin^2A)/1+cosA + (1+cosA)/sinA - (sinA)/1-cosA is
Read Solution (Total 1)
-
- 1- (sin^2A)/(1+cosA)+ (1+cosA)/sinA - sinA/(1+cosA)
1 - (sin^2A)/(1+cosA) + ((1-cos^2A)-sin^2A)/sinA(1-cosA)
(2nd term is 0 since 1-cos^2A=sin^2A)
on solving 1st term we get ans as cos A
answer= cosA - 12 years agoHelpfull: Yes(3) No(0)
