Integrate 3*x^2 + 1/x - x + 3
(3* (x^(2+1)) /3) + ln(x) - (x^2)/2 +3x
C = (4a + 3b) / 3, a = -3, b =2 What is C?
(4*(-3) + 3*(2) )/ 3 == -2
How does an airplane fly?
An airplane flies using three methods. An engine for propulsion, control systems such as ailerons and rudder for control and wings which provide lift. An engine uses compression and ignition of air to provide thrust. The three primary system of control in an aircraft is roll, pitch and yaw. Rudder (on the vertical tail) provides yaw, Aileron (on the wings) provide roll and the elevator (on the horizontal tail) provide pitch. Wings provide lift due to air rushing over them and creating a difference in pressure between the upper and lower surfaces of the wing
