please experts give me a detail soln

hello kusum i want detail soln

let f be a function from the set of all integers to set of all real numbers such that f(n+9)=f(n) & f(n+16)=f(n) show that f is a constant function

sin⁵x+cos³x=1 pls solve this equation &give me detailed soln

pls give me a detail solution

find the max among 1,2^1/2,3^1/3,4^1/4.......................

let f(x)=x⁴+ax³+bx²+cx+d wher a,b,c,d are integers. the sums of the pairs of roots of f(x) are given by 1,2,5,6,9and 10.find f(1/2)

solve sin⁵x+cos³x=1

chlorine is a deactivating group chlorine has lonepairs on it so it can activate the ring but due to its highelectronegativity its tendency to loose electrons is less and it attracts the electronsfrom the ring so it is a deactivating ortho-para group
