half angle formulae

If an angle of any measure be given, one can always construct (or draw) a cartesian co-ordinate reference frame in such a way that the origin is at the vertex of the angle, and positive half of the x axis coincides with the initial side of the angle. When th..

Draw a triangle ABC. Draw its angle bisectors. The angle bisectors pass through a point. Recall the procedure to draw angle bisectors: With B as centre and with a convenient radius draw an arc of a circle to cut AB and AC at X and Y. With X and Y as centres and..

The time required for the decay of the radioactive element to one half of its original amount is called Half-Life Period..

Half life of a reaction is defined as the time required for reducing the concentration of a reactant to half its initial value. It is denoted as t 1 / 2..

Half life of a reaction is defined as the time required for reducing the concentration of a reactant to half its initial value. It is denoted as t 1 / 2 . As discussed before, the t 1 / 2 of a zero order reaction is given as In general, for a reaction of order n, t 1 / 2 is prop..

Half-Life Period - The time required for the decay of the radioactive element to one half of its original amount is called Half-Life Period . It is denoted by t 1 / 2 . Putting these values in equation (iii), we g..

The Concept of Half-cell - A galvanic cell consists of two electrodes dipping into the same or two different electrolytes. No reaction takes place until a conducting wire joins the two electrodes. Once, a chemical reaction takes place at each electrode, electron transfer takes place. The ..

In these half-reactions, the number of electrons lost and gained are not equal. These can be made equal by multiplying the above reaction at the cathode by..

The net cell reaction can be obtained by adding these two equations...

Reflex Angle : An angle whose measure is more than 180 o and less than 360 o is called a reflex angle..
