cos^2A + 1/1+cot^2A=1


AbhishGS: cos.sq.A+1/(1+cot.sq.A) = cos.sq.A+1/cosec.sq.A = cos.sq.A+sin.sq.A =1
yashbarik: please explain this
AbhishGS: if u know formulae then u will get how it came
AbhishGS: look out every formulas and identities u have

Cos.sq.A+1/(1+cot.sq.A)=1
LHS = cos.sq.A+1/(1+cot.sq.A)

=cos.sq.A+1/cosec.sq.A.
....(1+cot.sq.A=cosec.sq.A).
.(.1/sinA=cosecA)
: . cos.sq.A+sin.sq.A...(sin.sq.A+cos.sqA)=1
= 1
