Let f:N→N be defined as f(n)=n+12 if n is odd and f(n)=n2 if n is even for all n∈N State whether the function f is bijective. Justify your answer
Let p(x) be a polynomial with real coefficients. Let a and b (with a < b), be two consecutive zeroes of p(x). If a < c < b then find the value of p 0 (c) + 10p(c).
Cos theta+sin theta=2cos theta show that cos theta-sin theta=2sin theta
