Question

Limit 1-COSX/SINX
x->0

Answer 1

$heya \\ \\ \\ \\ lim \: \: \: \: \: \: \: 2 \sin {}^{2} (x \div 2) \div \sin(x) \\ x - > 0 \\ \\ \\ lim \: \: \: \: 2 \times (\sin(x \div 2) \div (x \div 2) ) {}^{2} \times x {}^{2} \div 4 \div ( \sin(x) \div x) \times x \\ x - > 0 \: \: \: \: \: \\ \\ \\ = 0$
