If `5 leq 4K +1 leq 29`, then find the maximum number of co-primes formed from the possible valuesof K?

If |z+4| leq 3 then the maximum value of |z+1| is

If 0 leq theta leq pi and sin(theta/2)=sqrt(1+sintheta)-sqrt(1-sintheta) , then the possible value of tan theta is (a) 4/3 (b) 0 (c) -3/4 (d) -4/3

Show that there are an infinite number of primes of the form 4k + 1 and of the form 4k+ 3.

If |z-4+3i| leq 1 and m and n be the least and greatest values of |z| and K be the least value of (x^4+x^2+4)/x on the interval (0,oo) , then K=

If |z-4+3i| leq 1 and m and n be the least and greatest values of |z| and K be the least value of (x^4+x^2+4)/x on the interval (0,oo) , then K=
