Mkuu samahani electric device nadhani ni vifaa vinavyozalisha umeme au kutumia umeme kuzalisha aina nyingine ya nishati mfano jenereta na bulb, Ila electronic devices ni vifaa vinavyoweza kuonesha picha,kutoa au kurekodi sauti ,kuandika maandishi na vitu vinavyofania ni hivyo mfano simu,tv,redio na kamera lakini vina mfumo wa umeme ndani yakeElectric device these are the device which operate due to the presence of electricity
These are powered by electricity, exampes are tv, radio machines and lumps.
Electronic device are the devices which contral the flow of electricity in the electric devices.
Examples are diodes, transistor and ic's

logx^2=x/25Solve for x if logx2=x/25
note x2 ni x square
Swali la ivyo halipo
Acha njia fekilogx^2=x/25
Consider R.H.S and introduce log10
logx^2=x/25log10.
but x/25=4x/100.
Hence,
logx^2=4x/100log10
logx^2=x/100log10^4.
logx^2=x/100log100^2.
By comparison between LHS and RHS
x^2=100^2.
x=100.
Or
1=x/100.
x=100.
OK, nikutakie siku njema.Acha njia feki
Mkuu umepata banaOK, nikutakie siku njema.
SOLUTIONSolve CosA +tanA if sin A =12 /13
SOLUTION
by using right angled tranglle method
Let A=angle
There fore
12=opposite
13=hypotenuse
To know other side use pythograss theory(let other side be x)
X² = Hyp² - Opp²
X²= 13² - 12²
X² = 169 - 144
X²= 25 (underfoot both sides)
You get
X=5. This is adjacent
Recall
Cos A = adjacent/hypoten
Cos A= 5/13
Also
Tan A= opp/adj
Tan A= 12/5
TanA+ cosa
12/5 +5/13= 17/65. (Ans )
