It’s called the small angle approximation, so it’s not exactly equal until theta=0, but it’s close enough that it can save you a trip to the trigonometric tables. It was handy more than 40 years ago, before trigonometric functions were widely available on calculators. Use trigonometric tables on a day’s worth of work and you’ll appreciate the shortcut.
Theta used in physics are in radians and to some value the normal radians or trigonometric functions of that value of radian is almost the same that's why
Thank u sir it help me a lot during exam
You are most welcome
Spectacular
thank you so much for liking
Tq u so much
You are most welcome
How tan thita is become only thita but value of thita and tan thita are always different (in case of small thita also)🤔🤔
Tan0 is equal to 0
