# Thread: Finding the length of a curve ??

1. ## Finding the length of a curve ??

Consider one arch of y=sin(x) for 0 <= x <= pi

Write an integral whos value is the length of this curve ??

Ok this is my first time seeing a question where it asks to find the Length of a curve ??

so how do i begin ??

If you've been asked this question then you must have been taught the arclength formula. Go back and look in your class notes and/or textbook.

3. hmm are you refering to L= R@ ??

this was in our past exam papers ???

the thing is- it said using integration ???
