Question

(1-cos^2x)(1+cot^2x)=1

Answer 1

\[(1-\cos ^{2}x) (1+\cot ^{2}x)=1\]
\[Formula : 1=\sin ^{2}x+\cos ^{2}x\]
\[cosec ^{2}x=1+\cot ^{2}x\]
\[(\sin ^{2}x+\cos ^{2}x-\cos ^{2}x)(cosec ^{2}x)=1 \]
\[\sin ^{2}x \times cosec ^{2}x=1\]
\[1=1\]

Answer 2

@daya128 how about that ???

Answer 3

wats cosec^2x?
