so rearrange the given equation into
cosec100x = 1 – tan100x ….......1
according to equation 1 cosec100x is always less than 1 since tan100x is always greater than equal to zero
but according to our knowledge cosec 100x is always greater than equal to zero
so tan100x = 0 ….............2
so x = 0 (one soluytion) but this solution does not satisfy that cosec100x =1
then for no value of x this equation can be correct .
