Structure: The respiratory system starts at the mouth and nose with the pharynx, and continues as the trachea - this is covered with the epiglottis that prevents food and other material entering the lower ai...

If f(x) = 4x - m, and g(x) = mx +11, then the combined functions are: fg(x) = 4(mx +11) -m, or expanded to fg(x) = 4mx + 44 - m. We are told that this function of 'f' and 'g' can also be written as fg(x) = 8...

Use a double-bracket expansion method such as FOIL (first, outer, inner, last). If you don't know FOIL or how to expand double brackets, don't worry, I will explain it to you in the session. 6x 2 - 3x + 4x -...

Integrate by parts. First rewrite the integral in the form u dv/dx, which is (1)ln(x). Then integrate (1)ln(x) wrt dx by assigning u=ln(x) du/dx=1/x and dv/dx=1 v=x. We can determine the integral of ln(x), u...
