Use L'Hopitals Rule to find the limit of cosh x - cosh a / sinh x - sinh a at a

In this tutorial we find the limit of cosh x - cosh a / sinh x - sinh a , The initial value at zero gives us a 0/0 situation which is undefined . This is one of the rules required for L'Hopital . The other is that the function f(x)/g(x) where f(x) and g(x) are both continuous and differentiable . Then we take the lim x approaches 0 of f'(x)/g'(x) .. Here using a limit approaching a variable we get the unusual result which includes the variable at tanh a    • Find the Limit of a Function using L'Hôpit...      • Use L'Hopitals Rule to find the limit of s...      • Using L'Hôpital's Rule to Find The Limit   #calculus #limits #algebratricks #limitsandderivatives #derivativeformulas #derivativeofcos #lhopital #realanalysis #calc3 #sumchief #somesums
