Extreme Value Theorem: If f is continuous on a closed interval [a,b] then f has both an
absolute maximum and minimum on the interval [a,b].
Mean Value Theorem: If y=f(x) is continuous on a closed interval [a,b] and is differential in [a,b]
then at least o
Find the function with the given derivative whose graph passes through the point p.
a) f(x) = cos(x) + sin(x) + 2, P(,3)
f(x) = -cos(x) + sin(x) + C
f() = -cos() + sin() + c = 3
1+0+c=3
c=2
F(x) = -cos(x)+sin(x)+2
b) f(x) = 1/x+3, P(-2,4)
f(x) = n(x+3)+c
A car accelerates from rest at the beginning of an entrance ramp. It accelerates at a steady rate
of 15ft/sec. The ramp is 300 feet long. How fast is the car going at the end of the ramp?
a(t) = 15
v(t) = 15t
s(t) = 7.5t=300
t=40
t=40
t=6.325sec
v(6.325)
A particle starts at x=0 and moves with a velocity of v(t)=t+2. Where is the particle at t=3 sec?
Use 3 subdivision with LRAM, RRAM, and MRAM.
LRAM - 1(2+3+6) = 11 ft, Underestimate
RRAM - 1(3+6+11) = 20ft, Overestimate
MRAM - 1(2.25+4.25+8.25) = 14.75ft

As the EB junction is forward biased the holes from emitter region flow towards the base

We know that IC = IB + (1+) ICBO where ICBO is the reverse saturation current. As the

This d.c. voltage is called bias voltage.
As the input circuit has low resistance, a small change in the signal voltage Vi causes a
large change in the base current thereby causing the same change in collector current
