Factorisation of algebra

factorise completely p+q-(3p^2)+(3q^2)-Hi friend, p + q - 3p^2 + 3q^2 = p + q+ 3(q^2-p^2) = p + q+ 3(q-p)(p+q) = (p+q) (1 + 3(p-q) = (p+q) (1 + 3p - 3q)-p+q-(3p^2)+(3q^2) = p - (3p^2) + q+(3q^2

Sin theta= the side opposite an angle less than 90 degree divided by the length of the hypotenuse.

So i wanna know that what does the length of the side opposite an angle less than 90 degree call in short form like hypotenuse. And next to an angle less than 90degree=what in short form?-Those would

Prove the order gH must divide order of g....help

Let G be a finite group and let H be a normal subgroup of G. Prove that the order of the element gH in G/H must divide the order of g in G. A hint in the book said order of g = n and to suppose (gH)^

Calculus Problem Help.

Suppose f is differentiable and that there are points x1 and x2 such that f(x1)=x2 and f(x2)=x1. Let g(x) = f(f(f(f(x)))). Show that g(x1)=g(x2).-g(x1) = f(f(f(f(x1)))) g(x1) = f(f(f(x2))) g(x1) = f(f
