Methods of proving the Standard limit Sin(x)/x_part 1

This is part 1 of the discussion for the Standard limit. In these two videos we will use different techniques/methods to prove the statement. Correction : In the last part the inequality should be cos(theta) less than equal to sin(theta)/theta less than equal to 1 Proof: https://drive.google.com/file/d/14fCdgw70nVVsqBrOTgpKPm1IPa7QYv88/view?usp=drivesdk
