f(x) = x^3 + 3x^2 + 5. Find f''(x)

f''(x) means that we need to differentiate the function f(x) twice (f'(x) would mean we need to do it once). Differentiation means we multiply the coefficient by the power, and subtract one from the power. So: f'(x) = 3x^2 + 6x f''(x) = 6x + 6

Why is there more than one solution to x^2 = 4?


Show, by counter-example, that the statement "If cos(a) = cos(b) then sin(a) = sin(b)" is false.


A particle A rests on a smooth inclined plane, it is connected to a particle B by a light inextensible string that is passed over a fixed smooth pulley at the top of the plane. B hangs freely. Find the acceleration of the system and tension in the string.
