Find the no. of points of discontinuity of f(x) = (1+cos5x) / (1-cos4x)
since cos function is continuous throughout the R , we need to check the denominator which must not be zero . 1-cos4x=0 => x=npi/2 , n=integer so domain = R- { npi/2 | n is an integer }

so domain = R- { npi/2 | n is an integer }
Hi the function would be discontinuous at the points that it is not defined Those points are : x=npi/2
