Why you use tetrode instead of triode?
a tetrode is used when you need a screen grid tube, but a suppressor grid tube can't be used.OK, but the question was "why use a tetrode instead of a triode?"So, the answer...1. A tetrode has a higher voltage/power gain than a triode.2. A tetrode has less anode-grid feedback capacitance than a triode, and can operate in common-cathode radio frequency circuits without the neutralisation (or other corrective circuitry) that is needed by a triode.
What is the tetrode?
Twin-grid vacuum tube

Does anybody know what a tetrode transistor was?
Yes. It was an early attempt to improve high-frequency operation.The device had the usual emitter-base-collector construction, but with *two* base connections, one at either side.In operation, a reverse bias applied to one of the base connections forced the current flow towards the other base, giving an artificially-narrow current path.This reduced capacitances in the device, giving higher operating frequencies.Concurrent, and later, developments gave greatly imrpoved perfomance from the conventional "triode" construction, so tetrode transistors became obsolete.Be aware that the tetrode transistor is basically a triode (three-electrode) device, unlike the vacuum tube tetrode, which has four terminals and gives radically different characteristics from the triode vacuum tube.
What problem in Triode vacuum tubes is solved by the screen grid in Tetrode vacuum tubes?
The screen grid shields the control grid from the plate, reducing capacitance and the Miller Effect, improving performance at high frequencies.It *also* greatly increases the intrinsic ("natural") gain.This is the amplification factor, "mu".A triode has a maximum mu of around 100, and as little as 2.0, depending on the valve type.A tetrode/pentode has a mu in excess of 500, often in the thousands.However, you won't usually find a specification for mu in tetrode/pentode data sheets, as it's impractical to design circuits with this amount of gain.Around 300~350 is the practical maximum.
What the correct schematic symbol of a tetrode tube?
The correct schematic symbol for a tetrode tube includes the usual elements for a vacuum tube - a cathode, anode, grid, and screen grid. The grid is depicted as a single line inside the tube with an arrow pointing towards the cathode. The screen grid is often shown as a grid between the control grid and the anode.
