hi all, I m taking this course to pursue a career in physics.
1) How to know whether a given function is differentiable ?
2) Also, as far as i know, calculus is an extension of geometry and algebra to deal with rate of change and area under curves. But I see some examples of certain functions (like f(x) = |x|, whose graph is a straight line) being differentiated.
Could some one help me with this ?
